目前多光轴系统的光轴平行度的检测方法有多种，现有的检测方法中，对光轴的确立主要依靠轮廓测量的方法，轮廓测量有两种方式：干涉测量与坐标测量，其中，干涉测量需要建立基准，不论是标准的补偿镜还是计算全息图，都存在的一定误差，导致检测结果不准确；坐标测量分为直角坐标测量与球坐标测量，直角坐标测量精度依赖于平移组件的精度，而球坐标测量装置受制于角位移测量，导致检测方法步骤繁琐，因此，对于多光轴系统来说，上述方法测量的光轴平行度并不是最佳的方法。At present, there are many methods for detecting the parallelism of the optical axes of the multi-axis system. Among the existing detection methods, the establishment of the optical axis mainly depends on the method of contour measurement. There are two methods of contour measurement: interferometry and coordinate measurement. , Interferometric measurement needs to establish a benchmark, whether it is a standard compensation mirror or a computational hologram, there are certain errors that lead to inaccurate detection results; coordinate measurement is divided into rectangular coordinate measurement and spherical coordinate measurement, and the accuracy of rectangular coordinate measurement depends on the translation component The precision of the spherical coordinate measuring device is limited by the angular displacement measurement, which leads to cumbersome detection method steps. Therefore, for the multi-optical axis system, the above method to measure the parallelism of the optical axes is not the best method.
因此，如何提高多光轴系统的光轴平行度的准确性并简化检测步骤是本领域技术人员需要解决的技术问题。Therefore, how to improve the accuracy of the parallelism of the optical axes of the multi-optical axis system and simplify the detection steps is a technical problem to be solved by those skilled in the art.

步骤S1：激光器1发射准直光至中转元件2，经过所述中转元件2后形成与主光学元件3的理想光轴平行的准直光。Step S1: the laser 1 emits collimated light to the relay element 2, and after passing through the relay element 2, collimated light parallel to the ideal optical axis of the main optical element 3 is formed.
其中，中转元件2将激光器1的准直光中转至主光学元件3的理想光轴平行的方向。对准直光是否与理想光轴平行进行校正，具体的，通过两维偏摆的方式调节，保证改变中转元件2的位置时，准直光通过中转元件2以及主光学元件3后落在靶面4的光斑位置不变，表明准直光与理想光轴平行。同时，激光器1无需与主光学元件3对准，只要中转元件2与主光学元件3对准即可，同时利用中转元件2避免了调节激光器1的准直光方向与理想光轴方向容易产生的偏差。Wherein, the relay element 2 relays the collimated light of the laser 1 to a direction parallel to the ideal optical axis of the main optical element 3 . Correct whether the collimated light is parallel to the ideal optical axis, specifically, through the adjustment of two-dimensional deflection, to ensure that when the position of the relay element 2 is changed, the collimated light falls on the target after passing through the relay element 2 and the main optical element 3 The position of the spot on surface 4 remains unchanged, indicating that the collimated light is parallel to the ideal optical axis. At the same time, the laser 1 does not need to be aligned with the main optical element 3, as long as the transfer element 2 is aligned with the main optical element 3. At the same time, the use of the transfer element 2 avoids the easy occurrence of adjusting the collimated light direction of the laser 1 and the ideal optical axis direction. deviation.

In this embodiment, the laser 1 and the transfer element 2 are placed on a guide rail, and the guide rail is installed above the entire system. The guide rail can be rotated with the focus as the center of the circle, and the transfer element 2 moves on the guide rail while rotating the guide rail itself. To realize the scanning of any position of the relay element 2 within the radius of rotation, so as to scan each sub-optical element 5 to be measured.
步骤S4：依次判断所述光斑是否与靶面4中心重合，若否，则根据所述光斑与所述靶面4中心之间的偏离距离调节所述待测子光学元件5的光轴相互平行。Step S4: sequentially judge whether the light spot coincides with the center of the target surface 4, if not, adjust the optical axes of the sub-optical elements 5 to be tested to be parallel to each other according to the deviation distance between the light spot and the center of the target surface 4 .
其中，移动中转元件2至各个待测子光学元件5上方，激光器1发射准直光至中转元件2，中转元件2将准直光经待测子光学元件5反射后至靶面4上，形成光斑，判断所述光斑是否与靶面4中心重合，若否，则根据所述光斑与所述靶面4中心之间的偏离距离计算光轴偏移量，根据光轴偏移量调节各个待测子光学元件5的光轴相互平行。Wherein, the transfer element 2 is moved above each sub-optical element 5 to be tested, the laser 1 emits collimated light to the transfer element 2, and the transfer element 2 reflects the collimated light to the target surface 4 after being reflected by the sub-optical element 5 to be measured, forming Light spot, judge whether described light spot coincides with the center of target surface 4, if not, calculate the optical axis offset according to the deviation distance between the described light spot and the center of the target surface 4, adjust each waiting position according to the optical axis offset The optical axes of the sub-optics 5 are parallel to each other.
通过中转元件2将激光器1的发射光转换为与主光学元件3理想光轴平行的准直光，记录在靶面4中心的光斑，之后通过移动中转元件2到各个待测子光学元件5上方，同样进行激光反射，在靶面4上的光斑与靶面4中心的偏离进行光轴平行度的调节。由于多光轴光学系统中包括了主设备与多个辅助设备，因此，在一个辅助设备的光轴调节结束后，接着对另一个辅助设备进行装调，直至全部子系统的轴线误差得到检测并装调完成。高多光轴系统的光轴平行度的准确性并简化检测步骤。The emitted light of the laser 1 is converted into collimated light parallel to the ideal optical axis of the main optical element 3 through the relay element 2, and the light spot in the center of the target surface 4 is recorded, and then the relay element 2 is moved to the top of each sub-optical element 5 to be measured , laser reflection is also carried out, and the deviation of the spot on the target surface 4 from the center of the target surface 4 is used to adjust the parallelism of the optical axis. Since the multi-optical axis optical system includes the main device and multiple auxiliary devices, after the optical axis adjustment of one auxiliary device is completed, the other auxiliary device is then adjusted until the axis errors of all subsystems are detected and corrected.

其中，由于五棱镜能够将入射准直光转换为与入射的准直光垂直的准直光，无论如何旋转五棱镜，均能够实现上述效果，因此，利用五棱镜能够Wherein, since the pentaprism can convert the incident collimated light into the collimated light perpendicular to the incident collimated light, no matter how the pentaprism is rotated, the above-mentioned effects can be achieved. Therefore, the use of the pentaprism can
需要指出的是，包括但不限于五棱镜，还可以为倾角为45度的平面镜等，均在保护范围内。It should be pointed out that, including but not limited to a pentaprism, it can also be a plane mirror with an inclination angle of 45 degrees, etc., all of which are within the scope of protection.
