示例地，如图3所示，回转体椭圆球面镜包括一体设置的椭圆球体和圆柱体，椭圆球体的入射面为椭圆球面、出射面通过平面和圆柱体的端面连接。For example, as shown in FIG. 3 , the ellipsoidal mirror of the gyrosphere includes an ellipsoid and a cylinder integrally arranged. The incident surface of the ellipsoid is an ellipsoid, and the exit surface is connected to the end surface of the cylinder through a plane.
回转体椭圆球面镜可看成前端由椭圆球体和后端由圆柱体形成的一体结构，椭圆球体的入射面为椭圆球面，椭圆球体的出射面为平面，平面的出射面和圆柱体的端面连接一体。The elliptical spherical mirror of a revolution body can be regarded as an integrated structure formed by an elliptical sphere at the front end and a cylinder at the rear end.

对于光导模块103来说，光导模块103包括光波导，光束通过光波导的内壁反射后由光波导的耦出面出射。As for the
光波导的内壁反射光束，进入光波导的光束由光波导内壁反射后经耦出面出射，由于光束在内壁上不同位置反射后的角度不同，因此最终反射后由耦出面出射的光束的位置也不同，光束在光波导内进行反射叠加，输出的光束能量分布均匀，可得到均匀的光斑。The inner wall of the optical waveguide reflects the light beam, and the light beam entering the optical waveguide is reflected by the inner wall of the optical waveguide and exits through the coupling surface. Since the angle of the light beam reflected at different positions on the inner wall is different, the position of the beam exiting the coupling surface after the final reflection is also different. , the light beams are reflected and superimposed in the optical waveguide, the energy distribution of the output light beams is uniform, and a uniform light spot can be obtained.
光波导的具体设置不同，其得到的均匀光斑的尺寸大小也不同；示例地，光波导的耦入面小于或等于耦出面。Depending on the specific configuration of the optical waveguide, the size of the uniform light spot obtained is also different; for example, the coupling surface of the optical waveguide is smaller than or equal to the coupling surface.
光束从光波导的藕入面进入光波导，由光波导的耦出面出射；当光波导的藕入面小于耦出面时，即藕出面尺寸较大，此时光波导相当于一个具有大喇叭口的结构，可将光束在耦出面进行扩散，则输出的光斑尺寸也较大，可得到均匀大光斑。The light beam enters the optical waveguide from the coupling-in surface of the optical waveguide, and exits from the coupling-out surface of the optical waveguide; when the coupling-in surface of the optical waveguide is smaller than the coupling-out surface, that is, the size of the coupling-out surface is larger, at this time the optical waveguide is equivalent to a large bell mouth The structure can diffuse the beam on the outcoupling surface, so the output spot size is also larger, and a uniform large spot can be obtained.
当藕入面等于藕出面时，则光波导相当于一个直筒结构，可输出均匀光斑，但是输出的均匀光斑尺寸小于耦出面尺寸较大时得到的光斑尺寸。可见，光波导的设置可影响输出的光斑尺寸大小，实际应用时，可根据具体需要设置光波导的尺寸和形状，此处不再赘述。When the coupling-in surface is equal to the coupling-out surface, the optical waveguide is equivalent to a straight cylinder structure, which can output a uniform light spot, but the output uniform spot size is smaller than that obtained when the coupling-out surface is larger. It can be seen that the setting of the optical waveguide can affect the size of the output spot. In practical applications, the size and shape of the optical waveguide can be set according to specific needs, which will not be repeated here.
图7示出了光学模组出射的光束在光波导出口处的光斑能量分布图；Fig. 7 shows the spot energy distribution diagram of the light beam emitted by the optical module at the exit of the optical waveguide;
图8和图9分别示出了上述光学模组出射的光束在X轴(快轴)和Y轴(慢轴)方向的切面能量分布曲线图，由图中可看出，输出的光束能量分布呈平顶状，可得到均匀光斑。Figure 8 and Figure 9 respectively show the sectional energy distribution curves of the light beam emitted by the above-mentioned optical module in the directions of the X-axis (fast axis) and the Y-axis (slow axis). It can be seen from the figure that the output beam energy distribution It is flat-topped and can get a uniform spot.

其中，光源为半导体激光器；由于半导体激光器光源的发射场存在严重的像散问题，例如对于LD激光器快轴和慢轴两个方向的发散角大小不同，或者光源发光面在两个方向的尺寸(长和宽)不同，均存在严重像散问题，难以输出短距离均匀大光斑；本申请通过设置上述的光学模组，使得半导体激光器光源出射的光束，经过上述光学模组后，其快轴、慢轴的发散角一致，解决了上述像散问题，实现短距离下的均匀大光斑的输出。Wherein, the light source is a semiconductor laser; because the emission field of the semiconductor laser light source has serious astigmatism problems, for example, the divergence angles in the two directions of the fast axis and the slow axis of the LD laser are different, or the size of the light emitting surface of the light source in the two directions ( length and width), there is a serious astigmatism problem, and it is difficult to output a short-distance uniform large spot; the application sets the above-mentioned optical module, so that the light beam emitted by the semiconductor laser light source passes through the above-mentioned optical module, its fast axis, The divergence angle of the slow axis is consistent, which solves the above-mentioned astigmatism problem and realizes a uniform and large spot output at a short distance.
