Description
Translated fromChinese技术领域technical field
本发明涉及光路调节技术领域，特别是涉及一种反射镜架及其应用方法。The invention relates to the technical field of optical path adjustment, in particular to a reflecting mirror frame and an application method thereof.
背景技术Background technique
如图1所示，现有的反射镜架的支撑杆旋转中心轴线通常与镜片反射面中心点之间存在较大的偏离尺寸W，偏离尺寸W可达镜架所适合安装的镜片直径的1/2，这使得现有的反射镜架在许多场合并不好用。比如在光路布置中，通过在光路上的某一点处安装反射镜架及反射镜来实现对光束的转折，一般操作流程为：先将安装了反射镜的镜架初步摆放一个位置，使入射光投射到镜片中心区域，然后通过镜架的支撑杆旋转带动镜架及镜片一起转动实现镜片安装角度的粗调，再用镜架上的调节螺钉实现对镜片安装角度的微调。但由于偏离尺寸W的存在，在用旋转支撑杆来粗调镜片安装角度时，常常出现光的入射点明显偏离反射镜面中心区域，甚至离开镜面的问题，从而导致镜架安装失败，因此采用现有的反射镜架进行光路布置时，需要反复地调整镜架位置和角度，光路布置和调整麻烦且复杂。As shown in Fig. 1, there is usually a large deviation dimension W between the rotation center axis of the support rod of the existing mirror frame and the center point of the reflective surface of the lens, and the deviation dimension W can reach 1 % of the diameter of the lens suitable for the installation of the mirror frame. /2, which makes the existing mirror frame unusable in many occasions. For example, in the optical path arrangement, the turning of the light beam is realized by installing a reflector frame and a reflector at a certain point on the optical path. The light is projected to the central area of the lens, and then the support rod of the frame is rotated to drive the frame and the lens to rotate together to realize the coarse adjustment of the lens installation angle, and then use the adjustment screws on the frame to realize the fine adjustment of the lens installation angle. However, due to the existence of the deviation dimension W, when using the rotating support rod to roughly adjust the lens installation angle, the incident point of the light often deviates significantly from the central area of the reflective mirror surface, or even leaves the mirror surface, resulting in the failure of the mirror frame installation. When arranging the optical path of some reflector frames, it is necessary to adjust the position and angle of the mirror frame repeatedly, which is troublesome and complicated to arrange and adjust the optical path.
换句话说，在采用反射镜架进行光路布置和调整时，一般希望其安装的反射镜片对光的入射点靠近镜面的中心点，但因现有的反射镜架上较大偏离尺寸W的存在，采用现有反射镜架进行光路调节时经常会面临以下问题，使光路调节比较繁琐耗时：1）在粗调镜架方位而旋转支撑杆时，在偏离尺寸W的影响下，镜面中心点也会绕支撑杆轴线而旋转而产生较大位置改变，则入射光在镜面上的入射点也产生较大变化（本来入射光投射至镜面的中心区域，但镜面中心位置改变，故光入射点相对镜面产生变化），甚至离开镜面，如图2所示；2）为重新使光入射至反射镜反射面的中心区域，并调整镜片角度使光反射角度达到要求，在利用螺钉微调反射镜安装角度之前，往往需要多次重新调整支撑杆支座的位置、旋转与升降调节支撑杆，如此一来，会导致调节过程比较麻烦，而且调节的位置无法确定；3）当需要应用两个或多个反射镜的时候，采用一般的反射镜架来调节光路，调节时间会更长。In other words, when using the reflector frame for optical path arrangement and adjustment, it is generally desirable that the incident point of the reflector to be installed is close to the center point of the mirror surface, but due to the existence of a large deviation dimension W on the existing reflector frame , when using the existing mirror frame to adjust the optical path, the following problems are often faced, which makes the optical path adjustment cumbersome and time-consuming: 1) When the orientation of the mirror frame is roughly adjusted and the support rod is rotated, under the influence of deviation from the dimension W, the center point of the mirror surface It also rotates around the axis of the support rod to produce a large position change, and the incident point of the incident light on the mirror surface also changes greatly (original incident light is projected to the central area of the mirror surface, but the center position of the mirror surface changes, so the light incident point relative to the mirror surface), or even leave the mirror surface, as shown in Figure 2; 2) In order to re-enter the central area of the reflecting surface of the reflector and adjust the angle of the lens to make the light reflection angle meet the requirements, use screws to fine-tune the installation of the reflector. Before the angle, it is often necessary to re-adjust the position of the support rod support, rotate and lift the support rod for many times. As a result, the adjustment process will be troublesome, and the adjustment position cannot be determined; 3) When it is necessary to apply two or more When a single reflector is used, the general reflector frame is used to adjust the optical path, and the adjustment time will be longer.
总的来讲，现有的反射镜架因存在偏离尺寸W而存在导致光路布局和调节复杂、麻烦、耗时长的缺陷。In general, the existing mirror frame has the defects that the optical path layout and adjustment are complicated, troublesome, and time-consuming due to the deviation from the dimension W.

The rotation of the support rod produces changes, that is, it can ensure that the center of the reflecting surface of the mirror is the reflection point of the reflected beam, so when the support rod is rotated to roughly adjust the angle of the reflecting mirror, the beam will not deviate significantly from the mirror even if the rotation angle is large. The center point of the reflective surface greatly facilitates the layout and adjustment of the optical path.
通过对随后的描述和附图的理解，本发明进一步的目的和优势将得以充分体现。Further objects and advantages of the present invention will be fully realized by an understanding of the ensuing description and drawings.

换句话说，本发明通过将支撑杆的安装孔133设置在反射镜的反射面中心的正下方位置的方式，使得反射镜的反射面中心能够与支撑杆的中心轴线保持在同一直线上，以此消除了现有反射镜架存在的偏离尺寸，从而能够在旋转支撑杆以调节所述反射镜架10的大致方位时，确保反射镜的反射面中心不会随着支撑杆的转动而产生变化，即能够确保反射镜的反射面中心即为反射光束的反射点，以此在旋转支撑杆粗调反射镜面角度时，即使旋转角度较大光束也不会明显偏离镜片反射面的中心点，极大地方便了光路布局和调节。In other words, by arranging the mounting

下面对本发明的所述反射镜镜架应用于交错光路的衔接的具体方式进行说明。The specific manner in which the mirror frame of the present invention is applied to the connection of the staggered optical paths will be described below.
如图7所示，为方便叙述，假设交错光路的两个光路位于高度不同的两个水平面上，设两个水平面的高度差，即两个光路的距离为H0。一般地，至少用两个反射镜可实现光路的衔接，这两个反射镜应分别位于两光路，即入射光路L1、出射光路L2上，分别计为入射光反射镜Min、出射光反射镜Mout。为简化光路布置，可以将入射光反射镜Min、出射光反射镜Mout布置在一个与入射光垂直的横截面上。因本发明的所述反射镜架10的反射镜的反射面中心点基本在支撑杆安装孔的轴线上，故所选横截面与入射光、最终出射光的交点的正下方（在实际应用中，最终出射光的空间位置可通过反向照射一路光束来定位）即为镜架的支撑杆支座21的布置位置。如图8所示，在俯视图中，入射光反射镜Min、出射光反射镜Mout的方位基本满足光入射角等于出射角。As shown in FIG. 7 , for the convenience of description, it is assumed that the two optical paths of the staggered optical path are located on two horizontal planes with different heights, and the height difference between the two horizontal planes is set, that is, the distance between the two optical paths is H0. Generally, at least two mirrors can be used to connect the optical paths. These two mirrors should be located on the two optical paths, namely, the incident light path L1 and the outgoing light path L2, which are respectively counted as the incident light mirror Min and the outgoing light mirror. Mout. In order to simplify the optical path arrangement, the incident light mirror Min and the outgoing light mirror Mout can be arranged on a cross section perpendicular to the incident light. Because the center point of the reflecting surface of the reflecting mirror of the reflecting
下面分别针对交错光路的两种情况进行阐述：The following describes the two cases of interleaved optical paths:
第一种情况：当两交错光路的距离H0较小，要求反射镜的俯仰角在镜架的调节范围在4°之内时，所述反射镜架10的应用方法包括以下步骤：The first case: when the distance H0 of the two staggered optical paths is small, and the pitch angle of the mirror is required to be within 4° of the adjustment range of the mirror frame, the application method of the
步骤S1、选择两个反射镜和反射镜架进行光路布置，如图9所示，两个反射镜分别为入射光反射镜Min和出射光反射镜Mout。Step S1 , selecting two mirrors and a mirror frame for optical path arrangement, as shown in FIG. 9 , the two mirrors are the incident light mirror Min and the outgoing light mirror Mout respectively.
两交错光路的距离H0较小，反射镜俯仰角较小时，可通过微调入射光反射镜Min和出射光反射镜Mout的俯仰角以适应两光路的高度差，故两个反射镜即可将系统入射光和最终出射光在入射光反射镜Min和出射光反射镜Mout之间衔接起来。The distance H0 between the two staggered optical paths is small, and when the pitch angle of the mirror is small, the pitch angle of the incident light mirror Min and the outgoing light mirror Mout can be fine-tuned to adapt to the height difference between the two optical paths, so the two mirrors can connect the system. The incident light and the final outgoing light are connected between the incident light mirror Min and the outgoing light mirror Mout.
步骤S2、将垂直于入射光路的一个横截面分别与入射光路和出射光路的交点确定为入射光反射镜Min的第一空间反射点Z1和出射光反射镜Mout的第二空间反射点Z2；Step S2, the intersection of a cross section perpendicular to the incident light path and the incident light path and the exit light path are respectively determined as the first space reflection point Z1 of the incident light mirror Min and the second space reflection point Z2 of the exit light reflection mirror Mout;
步骤S3、分别在第一空间反射点Z1和第二空间反射点Z2下方布置好所述支撑杆支座21；Step S3, arranging the support rod supports 21 under the first space reflection point Z1 and the second space reflection point Z2 respectively;
步骤S4、分别将入射光反射镜Min、出射光反射镜Mout通过对应的反射镜架和支撑杆安装至对应的所述支撑杆支座21；Step S4, respectively installing the incident light reflecting mirror Min and the outgoing light reflecting mirror Mout to the corresponding support rod supports 21 through the corresponding reflecting mirror frames and support rods;
值得一提的是，在这一实施例中，所述支撑杆22的中心轴线和所述支撑杆支座21的中心轴线一致，即所述支撑杆22的旋转中心轴与所述支撑杆支座21的中心轴线平行，在本发明的一些实施例中，所述支撑杆22的旋转中心轴也可以垂直于所述支撑杆支座21的中心轴线，即所述反射镜架10在垂直于所述支撑杆支座21的中心轴线的方向安装于所述支撑杆支座21，如图11所示，本发明对此不作限制。It is worth mentioning that, in this embodiment, the central axis of the
步骤S5、通过旋转、伸缩对应的支撑杆分别完成对入射光反射镜Min和出射光反射镜Mout的水平方位角的粗调，使得入射光入射至入射光反射镜Min的中心区域，反射后照射至出射光反射镜Mout，使沿出射光路反向入射的光束入射至出射光反射镜Mout的中心区域，反射后照射至入射光反射镜Min；Step S5, respectively complete the coarse adjustment of the horizontal azimuth angle of the incident light mirror Min and the outgoing light mirror Mout by rotating and expanding the corresponding support rods, so that the incident light is incident on the central area of the incident light mirror Min, and then irradiated after reflection. to the outgoing light reflecting mirror Mout, so that the light beam that is reversely incident along the outgoing optical path is incident on the central area of the outgoing light reflecting mirror Mout, and then irradiated to the incident light reflecting mirror Min after being reflected;
步骤S6、通过两个所述反射镜架10的调节螺钉103，分别微调入射光反射镜Min和出射光反射镜Mout的水平方位角和俯仰角，使系统入射光经入射光反射镜Min在第一空间反射点Z1处反射后的光束能够朝第二空间反射点Z2处照射，使沿最终出射光路L2反向入射的光束经出射光反射镜Mout在第二空间反射点Z2点处反射后光束能够朝第一空间反射点Z1处照射，按光路可逆原理，这样基本完成对入射光、出射光的衔接。Step S6, through the adjustment screws 103 of the two mirror frames 10, respectively fine-tune the horizontal azimuth angle and the pitch angle of the incident light mirror Min and the outgoing light mirror Mout, so that the incident light of the system passes through the incident light mirror Min at the first position. The light beam reflected at one spatial reflection point Z1 can be irradiated at the second spatial reflection point Z2, so that the light beam that is reversely incident along the final exit optical path L2 is reflected at the second spatial reflection point Z2 by the exit light reflecting mirror Mout The light beam can be irradiated toward the first spatial reflection point Z1, and according to the principle of reversibility of the optical path, the connection between the incident light and the outgoing light is basically completed.
步骤S7、最终再微调与确认系统入射光经入射光反射镜Min和出射光反射镜Mout反射后的出射光刚好是沿出射光路L2的要求的方向，即完成光路的布局和调节。Step S7, finally fine-tuning and confirming that the outgoing light reflected by the incident light mirror Min and the outgoing light mirror Mout of the system is exactly along the required direction of the outgoing light path L2, that is, the layout and adjustment of the light path are completed.
第二种情况：两路交错光路的距离H0较大，要求反射镜的俯仰角超出镜架的调节范围时，即当入射光路和反射光路之间的高度差要求反射镜的俯仰角调节范围大于4°时，所述反射镜架10的应用方法包括以下步骤：The second case: the distance H0 of the two staggered optical paths is large, and the pitch angle of the mirror is required to exceed the adjustment range of the mirror frame, that is, when the height difference between the incident optical path and the reflected optical path requires that the pitch angle adjustment range of the mirror is greater than 4°, the application method of the
如图10所示，当两路交错光路的距离H0较大，要求反射镜的俯仰角超出镜架的调节范围时，入射光反射镜Min的反射光在高度方向无法照射到出射光反射镜Mout高度，这时可在入射光反射镜Min的正上方，与出射光反射镜Mout在同一高度处再布置一个中间反射镜Mmid，增加的光束空间反射点计为中间空间反射点Z1-2，使该中间反射镜Mmid对光束的入射角、反射角刚好在第一空间反射点Z1、第二空间反射点Z2所在横截面上。As shown in Figure 10, when the distance H0 of the two staggered optical paths is large and the pitch angle of the mirror is required to exceed the adjustment range of the mirror frame, the reflected light of the incident light mirror Min cannot irradiate the outgoing light mirror Mout in the height direction At this time, an intermediate reflector Mmid can be arranged directly above the incident light reflector Min and at the same height as the exit light reflector Mout, and the increased beam space reflection point is counted as the intermediate space reflection point Z1-2, so that The incident angle and reflection angle of the intermediate reflector Mmid to the light beam are just on the cross section where the first space reflection point Z1 and the second space reflection point Z2 are located.
即步骤S10、选择三个反射镜和反射镜架，三个反射镜分别为入射光反射镜Min、中间反射镜Mmid以及出射光反射镜Mout。That is, in step S10, three reflecting mirrors and a reflecting mirror frame are selected, and the three reflecting mirrors are the incident light reflecting mirror Min, the intermediate reflecting mirror Mmid and the outgoing light reflecting mirror Mout.
在这一种情况下，中间反射镜Mmid的主要角度的调整轴线，即中间反射镜Mmid对应的支撑杆的轴线位于与入射光路L1平行的方向，这时可使用图11所示的镜架支撑结构20，具体地，该镜架支撑结构20包括所述支撑杆支座21、安装于所述支撑杆支座21的第一支撑杆221，安装在所述第一支撑杆221上的支杆夹223以及延伸自所述支杆夹223的第二支撑杆222，所述第二支撑杆222安装在中间反射镜Mmid对应的所述反射镜架10的所述安装孔133处，以此通过旋转所述第二支撑杆222来调节中间反射镜Mmid的方位。In this case, the adjustment axis of the main angle of the intermediate reflector Mmid, that is, the axis of the support rod corresponding to the intermediate reflector Mmid is located in a direction parallel to the incident light path L1, and the mirror frame shown in FIG. 11 can be used to support
应该理解的是，由于本发明的所述反射镜架10包括L形结构的所述支撑杆安装结构13，因此所述反射镜架10无论是在竖直方向还是垂直方向安装于所述支撑杆支座21，安装于所述反射镜架10的支撑杆的旋转中心轴线始终被保持与所述反射镜架10的所述反射镜的反射面中心点在同一直线上。It should be understood that, since the
相应地，入射光反射镜Min对光束的入射角、反射角变为在经过入射光所在入射光路L1的竖直面内，则入射光反射镜Min对应的镜架支撑杆轴线也在水平方向，并垂直于入射光路L1，即入射光反射镜Min采用的镜架支撑结构20与中间反射镜Mmid相同，而出射光反射镜Mout对应的支撑杆轴线平行于所述支撑杆支座21。Correspondingly, the incident angle and reflection angle of the incident light mirror Min to the light beam become in the vertical plane of the incident light path L1 where the incident light is located, and the axis of the frame support rod corresponding to the incident light mirror Min is also in the horizontal direction, It is perpendicular to the incident light path L1 , that is, the mirror
步骤S20、在垂直于入射光路L1的一个横截面内确定分别对应于入射光反射镜Min、中间反射镜Mmid以及出射光反射镜Mout的第一空间反射点Z1、中间空间反射点Z1-2、第二空间反射点Z2的位置，其中该横截面分别与入射光路L1和出射光路L2的交点为第一空间反射点Z1和第二空间反射点Z2，所述中间空间反射点Z1-2位于第一空间反射点Z1的正上方、与第二空间反射点Z2处于同一高度。Step S20, in a cross section perpendicular to the incident light path L1, determine the first space reflection point Z1, the intermediate space reflection point Z1-2, which correspond to the incident light mirror Min, the intermediate reflection mirror Mmid, and the outgoing light reflection mirror Mout respectively. The position of the second spatial reflection point Z2, wherein the intersection of the cross section with the incident optical path L1 and the outgoing optical path L2 are the first spatial reflection point Z1 and the second spatial reflection point Z2, and the intermediate spatial reflection point Z1-2 is located at Right above the first space reflection point Z1 and at the same height as the second space reflection point Z2.
也就是说，中间反射点Z1-2分别与第一空间反射点Z1和第二空间反射点Z2的连线所在的直线均位于垂直于入射光路L1的该横截面内。That is to say, the lines connecting the intermediate reflection points Z1-2 and the first space reflection point Z1 and the second space reflection point Z2 respectively are located in the cross section perpendicular to the incident light path L1.
步骤S30、分别在第一空间反射点Z1、中间空间反射点Z1-2、第二空间反射点Z2下方布置好所述支撑杆支座21。Step S30: Arrange the support rod supports 21 under the first space reflection point Z1, the intermediate space reflection point Z1-2, and the second space reflection point Z2, respectively.
具体地，步骤S30包括步骤：Specifically, step S30 includes the steps:
步骤S31、将入射光反射镜Min通过对应的反射镜架、第一支撑杆221、第二支撑杆222及支杆夹223安装至第一支撑杆支座形成入射光反射镜组件，使安装于所述反射镜架10的安装孔133的第二支撑杆222位于水平方位。再通过整体移动该入射光反射镜组件、升降第一支撑杆221，使第二支撑杆222垂直于入射光路L1，并使入射光反射镜Mmid的反射面中心点大致位于第一空间反射点Z1处，然后固定第一支撑杆支座；Step S31, the incident light reflector Min is installed on the first support rod support through the corresponding reflector frame, the
步骤S32、将中间反射镜Mmid通过对应的反射镜架、第一支撑杆221、第二支撑杆222及支杆夹223安装至第二支撑杆支座形成中间反射镜组件，使第二支撑杆222位于水平方位。再通过整体移动该中间反射镜组件、升降第一支撑杆221，使第二支撑杆222平行于入射光路L1，使中间反射镜Mmid的反射镜面中心点大致位于中间空间反射点Z1-2处，然后固定第二支撑杆支座；Step S32, the intermediate reflector Mmid is mounted on the second support rod support through the corresponding reflector frame, the
步骤S33、在第二空间反射点Z2的正下方布置第三支撑杆支座，并将出射光反射镜Mout通过对应的反射镜架、支撑杆安装至该第三支撑杆支座；通过对支撑杆的升降调节镜片高度，使出射光反射镜Mout的反射面的中心点大致位于光路的第二空间反射点Z2处，然后固定第三支撑杆支座。Step S33, arranging a third support rod support directly below the second space reflection point Z2, and installing the outgoing light reflector Mout to the third support rod support through the corresponding reflecting mirror frame and support rod; The height of the lens is adjusted by the lifting and lowering of the rod, so that the center point of the reflection surface of the outgoing light reflecting mirror Mout is approximately located at the second spatial reflection point Z2 of the optical path, and then the third support rod support is fixed.
进一步地，所述反射镜架10的应用方法还包括以下步骤：Further, the application method of the
步骤S40、通过旋转、伸缩对应的支撑杆分别完成对入射光反射镜Min、中间反射镜Mmid、出射光反射镜Mout的水平方位角的粗调，使得入射光经入射光反射镜Min在第一空间反射点Z1反射后，能够朝中间反射镜Mmid的中间空间反射点Z1-2照射，使沿出射光路反向入射的光束经出射光反射镜Mout在第二空间反射点Z2反射后，也能够朝中间反射镜Mmid的中间空间反射点Z1-2照射；Step S40, respectively complete the coarse adjustment of the horizontal azimuth angle of the incident light reflector Min, the intermediate reflector Mmid, and the outgoing light reflector Mout by rotating and expanding the corresponding support rods, so that the incident light passes through the incident light reflector Min at the first point. After being reflected by the space reflection point Z1, it can be irradiated toward the intermediate space reflection point Z1-2 of the intermediate reflection mirror Mmid, so that the light beam that is reversely incident along the outgoing optical path is reflected at the second space reflection point Z2 by the outgoing light reflection mirror Mout, and is also reflected at the second space reflection point Z2. Can irradiate toward the intermediate space reflection point Z1-2 of the intermediate reflector Mmid;
步骤S50、分别调节入射光反射镜Min、中间反射镜Mmid以及出射光反射镜Mout对应的反射镜架的调节螺钉，从而分别微调入射光反射镜Min、中间反射镜Mmid以及出射光反射镜Mout的水平方位角和俯仰角，使入射光经入射光反射镜Min和中间反射镜Mmid反射后能够朝出射光反射镜Mout的第二空间反射点Z2照射，以此完成对入射光和出射光的衔接。Step S50, respectively adjust the adjustment screws of the mirror frame corresponding to the incident light mirror Min, the intermediate mirror Mmid and the outgoing light mirror Mout, so as to fine-tune the incident light mirror Min, the intermediate mirror Mmid and the outgoing light mirror Mout respectively. Horizontal azimuth angle and pitch angle, so that the incident light can be irradiated toward the second space reflection point Z2 of the outgoing light mirror Mout after being reflected by the incident light mirror Min and the intermediate mirror Mmid, so as to complete the connection between the incident light and the outgoing light .
步骤S60、最终再微调与确认入射光经入射光反射镜Min、中间反射镜Mmid以及出射光反射镜Mout反射后的出射光沿出射光路L2射出，则完成交错光路的衔接。Step S60 , finally fine-tuning and confirming that the incident light reflected by the incident light mirror Min, the intermediate mirror Mmid and the outgoing light mirror Mout is emitted along the outgoing optical path L2 to complete the connection of the staggered optical paths.
可以理解的是，本发明将支撑杆安装孔设置在镜片反射面中心的正下部后，通过旋转支撑杆改变镜架的大致方位时，镜片反射面的中心的竖直投影始终位于支撑杆的中心附件，即反射面的中心位置基本不变。而利用反射镜反射光束时一般用的反射点即为反射面的中心（或中心区域），这样旋转支撑杆粗调反射镜面角度时，即使旋转角度较大光束也不会明显偏离镜片反射面的中心点，极大地方便了光路布局和调节。It can be understood that, after the mounting hole of the support rod is arranged in the right lower part of the center of the reflection surface of the lens in the present invention, when the general orientation of the frame is changed by rotating the support rod, the vertical projection of the center of the reflection surface of the lens is always located at the center of the support rod. Accessories, that is, the center position of the reflective surface is basically unchanged. When using a reflector to reflect light beams, the generally used reflection point is the center (or center area) of the reflecting surface. In this way, when rotating the support rod to roughly adjust the angle of the reflecting mirror surface, the beam will not deviate significantly from the reflecting surface of the lens even if the rotation angle is large. The center point greatly facilitates the optical path layout and adjustment.
采用本发明的所述反射镜架10，在初定镜架摆放位置后，镜架的支撑杆支座本身的位置也即确定，然后直接将其固定即完成光路布置，不会因为出现镜面旋转后光束脱离镜面而需要进行多次松开支撑杆支座、重新放置支撑杆支座并找光束（寻找入射光的位置，使其重新入射至反射镜镜面的中心区域）、再固定支撑杆支座的繁琐过程，操作简单无反复。而且在支撑杆支座固定后，直接先后通过旋转、升降支撑杆及调节镜架上的微调螺钉，即可完成对光路的调节，省时省力。With the
也就是说，采用本发明的所述反射镜架10进行光路布置和调节时，初步摆放镜架时只需直接将反射镜的反射面中心点（或中心区域，如半径小于镜面半径的1/4）放置到光的反射点，再通过旋转、升降支撑杆粗调反射镜的镜面角度，通过对应的调节螺钉微调镜面角度，即可完成对交错光路的布置和调节，整个流程操作方便简单、耗时短。That is to say, when using the
总的来讲，采用本发明的所述反射镜架10及其应用方法，可快速地实现光路衔接应用场合中的反射镜布置、调节，为光路的布置、调节提供了极大便利。In general, using the
