背景技术Background technique
激光核聚变是目前普遍采用的一种人工可控核聚变，它在民用和军事上都具有十分重大的研究意义：为人类提供一种取之不尽的清洁核能源；用来研制无放射污染的核武器、发展高能激光武器；部分替代核实验。Laser nuclear fusion is a kind of artificial controllable nuclear fusion commonly used at present. It has very important research significance in both civilian and military fields: it provides an inexhaustible clean nuclear energy for mankind; it is used to develop radioactive pollution-free nuclear weapons, development of high-energy laser weapons; partial replacement of nuclear experiments.
因此，激光核聚变受到世界各核大国的高度重视，从20世纪70年代后半叶开始，俄、美、日、法、中、英等国相继开始高功率激光驱动器的研制。美国在此领域的研究处于领先地位，并于2009年正式建成包含192路的超大型激光驱动装置“NIF”；法国正在建设的MLF包含240路激光；日本也在酝酿建造大型激光驱动器，并计划在2015-2020年间完成可应用于发电的基础技术研究。中国也建立了一系列的激光驱动装置(星光系列、神光系列等)，2015年完成建设的国内最大的激光驱动装置“神光－Ⅲ”包含48路激光。Therefore, laser nuclear fusion has been highly valued by the world's nuclear powers. Since the second half of the 1970s, Russia, the United States, Japan, France, China, Britain and other countries have successively started the development of high-power laser drivers. The United States is in a leading position in research in this field, and in 2009 it officially built a super-large laser drive device "NIF" containing 192 channels; the MLF under construction in France contains 240 laser channels; Japan is also planning to build a large laser drive, and plans to Complete basic technology research that can be applied to power generation during 2015-2020. China has also established a series of laser drive devices (Xingguang series, Shenguang series, etc.), and the largest domestic laser drive device "Shenguang-Ⅲ", which was completed in 2015, contains 48 lasers.
然而，美国NIF在2010年的点火并不顺利，这在世界范围引起了较大的震惊。针对NIF随后的研究发现，激光的背向散射和聚变燃料的瑞利-泰勒不稳定性是问题的根源。在背向散射方面，美国有关方认为在Omega等其它激光聚变装置上已经进行了透彻的研究、清楚了激光打靶的物理过程，因而对NIF装置的背向散射研究重视不足。However, the ignition of NIF in the United States in 2010 was not smooth, which caused a great shock in the world. Subsequent research at NIF found that the backscattering of the laser light and the Rayleigh-Taylor instability of the fusion fuel were at the root of the problem. In terms of backscattering, relevant parties in the United States believe that Omega and other laser fusion devices have conducted thorough research and clarified the physical process of laser targeting, so they have not paid enough attention to the backscattering research of NIF devices.
国内对背向散射的研究起步也较早，并取得了大量的研究成果，但我们必须吸取美国NIF的教训，高度重视背向散射光的研究。2013年国内紧急启动了基于神光-Ⅲ主机的背向散射光研究项目，共建设8套背向散射测量系统，覆盖激光的四个打靶环角，且每个角度选取2路，形成环-环相互对比、同环相互验证的庞大的、系统性的测量系统。Domestic research on backscattering started earlier, and a lot of research results have been obtained, but we must learn from the lessons of NIF in the United States and attach great importance to the research of backscattered light. In 2013, the backscattered light research project based on the Shenguang-Ⅲ host was urgently launched in China, and a total of 8 sets of backscatter measurement systems were built, covering the four shooting ring angles of the laser, and 2 channels were selected for each angle to form a ring- A huge and systematic measurement system that compares rings and verifies each other with rings.
但是，系统还需要标定后才能使用。因为从靶点发出的背向散射光在经过一系列光学元件到达探测器过程中，每个光学元件对背向散射光都有一定程度的衰减，而衰减系数因波长而异；探测器上的测量值如何反映待测值是一个关键问题。国际上，一般通过对实验前的测量系统进行标定，获得测量值与待测值之间的定量关系，以便由实验值推算待测值。However, the system needs to be calibrated before it can be used. Because the backscattered light emitted from the target point passes through a series of optical elements and reaches the detector, each optical element has a certain degree of attenuation to the backscattered light, and the attenuation coefficient varies with wavelength; How the measured value reflects the measured value is a key issue. Internationally, the quantitative relationship between the measured value and the measured value is generally obtained by calibrating the measurement system before the experiment, so that the measured value can be estimated from the experimental value.
标定的焦点问题是如何模拟从靶点发出的、具有特定圆锥角的点光源。The focus problem of calibration is how to simulate a point light source with a specific cone angle emitted from the target point.
美国在标定时采用的是抽样标定的思路：即选用一台点激光器，模拟从靶点发出的某一根光线，使之通过待标系统，得到单点透过率；改变光线方向，获得光学系统口径内多点的标定数据，进而综合得到系统的光谱透过率。这种标定方法的优点是：对标定光源要求很低，只需选择一台波长合适、工作稳定的小激光器即可。缺点是：存在以点盖面的缺陷，标定的不确定度大；另外，每套系统需要单独搭建标定光源，耗时耗力。The United States adopts the idea of sampling calibration during calibration: that is, select a point laser to simulate a certain light emitted from the target point, and make it pass through the system to be marked to obtain a single point transmittance; change the direction of the light to obtain optical Calibration data of multiple points within the system aperture, and then comprehensively obtain the spectral transmittance of the system. The advantage of this calibration method is that the requirements for the calibration light source are very low, and only a small laser with a suitable wavelength and stable operation can be selected. The disadvantages are: there is a defect of covering the surface with points, and the calibration uncertainty is large; in addition, each system needs to build a calibration light source separately, which is time-consuming and labor-intensive.
国内神光-Ⅲ原型的标定系统借鉴了美国的标定方法，只不过它采用的是一个体积庞大、具有电源箱、水冷箱的激光器，移动不便。因此只能将其光束引向球形真空靶室的靶点，在靶室内架设反射镜控制光束方向，以进行单点标定。上述方案的实施得益于原型装置真空靶室直径小(2.4m)，人员站立其内能够轻松操作。The calibration system of the domestic Shenguang-Ⅲ prototype borrows from the calibration method of the United States, but it uses a bulky laser with a power box and a water cooling box, which is inconvenient to move. Therefore, the light beam can only be directed to the target point of the spherical vacuum target chamber, and a mirror is set up in the target chamber to control the beam direction for single-point calibration. The implementation of the above scheme benefits from the small diameter (2.4m) of the vacuum target chamber of the prototype device, which can be easily operated by personnel standing in it.
而神光-Ⅲ主机的靶室直径达6m，虽有设备输送平台，但人员需要进入真空靶室进行高空调试作业，危险且耗时；况且这种抽样标定的不确定因素较大。如果待测光路规模庞大，则这种方法的效率极低。The diameter of the target chamber of the Shenguang-Ⅲ main engine is as high as 6m. Although there is an equipment delivery platform, personnel need to enter the vacuum target chamber for high-altitude debugging operations, which is dangerous and time-consuming; moreover, the uncertain factors of this sampling calibration are relatively large. This method is extremely inefficient if the optical path to be measured is large in scale.

如图2所示，万向光束模拟头11包括第一旋转关节1111、第二旋转关节1112。As shown in FIG. 2 , the gimbal beam simulation head 11 includes a first rotary joint 1111 and a second rotary joint 1112 .
模拟靶点1109设置在第一旋转关节1111的旋转轴和第二旋转关节1112的旋转轴的交汇处，两个旋转关节转动时模拟靶点1109的位置始终保持固定不变。The simulated target point 1109 is set at the intersection of the rotation axis of the first rotary joint 1111 and the second rotary joint 1112 , and the position of the simulated target point 1109 remains fixed when the two rotary joints rotate.

第二旋转关节1112位于第二五棱镜1103和第二直角棱镜1104之间，且第二旋转关节1112的旋转轴与第二五棱镜1103的出射光路重合。The second rotary joint 1112 is located between the second pentaprism 1103 and the second rectangular prism 1104 , and the rotation axis of the second rotary joint 1112 coincides with the outgoing light path of the second pentaprism 1103 .
第一五棱镜1101的两侧均设置有瞄准相机1110，这种双目瞄准镜头类似于一双眼睛，瞄准的中心与模拟靶点1109重合。通过瞄准相机1110的放大成像以及双目瞄准的立体定位功能，可实现10μm的定位精度，确保模拟靶点1109位置的准确性。Aiming cameras 1110 are arranged on both sides of the first pentaprism 1101 , this kind of binocular aiming lens is similar to a pair of eyes, and the center of aiming coincides with the simulated target point 1109 .

However, in the present utility model, a pentaprism is arranged at the first rotary joint 1111 and the second rotary joint 1112, and the physical characteristic that the outgoing light of the pentaprism is always perpendicular to the incident light greatly reduces the debugging of the universal beam simulation head 11. difficulty.

以下结合具体实施例进一步说明本实用新型的工作原理和工作过程：Below in conjunction with specific embodiment further illustrate working principle and working process of the present utility model:
首先将万向光束模拟头11送入靶室13中。分布于第一五棱镜1101左右两侧的瞄准相机1110都瞄准模拟靶点1109,当DIM12将万向光束模拟头11送入靶室13时，根据瞄准相机1110的图像位置判断万向光束模拟头11是否运送到位。Firstly, the gimbal beam simulation head 11 is sent into the target chamber 13 . The aiming cameras 1110 distributed on the left and right sides of the first pentaprism 1101 are aimed at the simulated target point 1109. When the DIM12 sends the universal beam simulation head 11 into the target chamber 13, the universal beam simulation head is judged according to the image position of the aiming camera 1110. 11 Whether the delivery is in place.
第二步：打开激光器1，并调整铰链分束镜2和铰链反射镜3。从激光器1出射的光束经铰链分束镜2分为两束，其中经铰链分束镜2的透射光经监测反射镜4反射后进入监测功率计5，监测功率计5监测激光器1是否稳定；铰链分束镜2的反射光经铰链反射镜3反射后，穿过DIM12尾端的真空密封窗6进入DIM12。通过配合调节铰链分束镜2和铰链反射镜3，使铰链反射镜3的反射光束同时穿过第一准直孔7和第二准直孔9，反射光束过孔情况可通过相应的第一监测相机8和第二监测相机10远程监视。Step 2: Turn on the laser 1, and adjust the hinged beam splitter 2 and hinged mirror 3. The beam emitted from the laser 1 is divided into two beams through the hinged beam splitter 2, wherein the transmitted light through the hinged beam splitter 2 is reflected by the monitoring mirror 4 and then enters the monitoring power meter 5, and the monitoring power meter 5 monitors whether the laser 1 is stable; The reflected light of the hinged beam splitter 2 is reflected by the hinged mirror 3, and enters the DIM12 through the vacuum-sealed window 6 at the end of the DIM12. By adjusting the hinged beam splitter 2 and the hinged mirror 3, the reflected beam of the hinged mirror 3 passes through the first collimating hole 7 and the second collimating hole 9 at the same time, and the reflected beam can pass through the corresponding first collimating hole. The monitoring camera 8 and the second monitoring camera 10 monitor remotely.
如图2所示，穿过第二准直孔9的输入光束依次经过第一五棱镜1101、第一直角棱镜1102、第二五棱镜1103、第二直角棱镜1104、第三直角棱镜1105、第四直角棱镜1106、第一光束模拟镜头1107或第二光束模拟镜头1108，由第一光束模拟镜头1107或第二光束模拟镜头1108将光束恰好会聚于模拟靶点1109，第一光束模拟镜头1107和第二光束模拟镜头1108通过电机切换使用。As shown in Figure 2, the input light beam passing through the second collimation hole 9 passes through the first five prism 1101, the first right angle prism 1102, the second five prism 1103, the second right angle prism 1104, the third right angle prism 1105, the second right angle prism successively Four rectangular prisms 1106, the first beam simulation lens 1107 or the second beam simulation lens 1108, the beam is just converged on the simulation target point 1109 by the first beam simulation lens 1107 or the second beam simulation lens 1108, the first beam simulation lens 1107 and The second beam simulation lens 1108 is switched to use by a motor.
由于模拟靶点1109设置在第一旋转关节1111的旋转轴和第二旋转关节1112的旋转轴的交汇处，因此无论这两个旋转关节如何旋转，模拟靶点1109的位置始终不变，仅会聚于模拟靶点1109处的光束的方向发生改变，这些会聚于模拟靶点1109处的各路模拟光束1114即可看作是从模拟靶点1109处发出的、具有不同方向的各路背向散射光。Since the simulated target point 1109 is set at the intersection of the rotation axis of the first rotary joint 1111 and the second rotary joint 1112, no matter how the two rotary joints rotate, the position of the simulated target point 1109 is always the same, only converging The direction of the light beam at the simulated target point 1109 changes, and the simulated beams 1114 converged at the simulated target point 1109 can be regarded as backscattered beams with different directions emitted from the simulated target point 1109 Light.
