摘　　要：针对透射式光学系统的光轴无法直接寻找的问题,提出基于光学节点特征的光轴标定方法。采用该方法研究节点与等效节点的性质,通过观测焦面像点的位移变化来确定节点的位置以标定光学系统的光轴,依据此方法设计双向互标双自准直平行光管的光轴标定装置,其中成像接收端的抽插式结构设计可以有效避免波前误差的影响,最终验证光轴标定方法的可行性。实验结果表明,该方法具有较高的光轴标定精度以及广泛的适应性,透镜光学系统的光轴标定精度为7.7″,为空间光学及国防等领域的透镜光学系统提供一种测试装调辅助手段。The optical axis of a transmission optical system cannot be found directly. To solve this problem, an optical axis calibration method based on the characteristics of optical nodes is proposed. The method is used to investigate the characteristics of a node and an equivalent node, by observing the focal plane image point displacement change, the location of the node to calibrate the optical axis of the system is determined. Furthermore,based on this method, the bidirectional exchange standard double autocollimation optical axis calibration device of parallel light pipe is designed, including imaging thrusting at the receiving end type structure design, which can effectively avoid the influence of the wavefront error. Finally, the feasibility of the proposed method is verified.Experiment results show that the proposed method has high optical axis calibration accuracy and wide adaptability.The optical axis calibration accuracy of the lens optical system is 7. 7", which provides an auxiliary means for testing and adjusting lens optical systems in space optics and national defense fields.
