一种多光轴一致性的检测方法

Method For Detecting Coherence of Multiple Optical Axis

通过使用卡塞格林结构的平行光管,实现对多个光轴夹角之间的测量。并且提出了针对此系统使用经纬仪辅助测量的方法,系统通过二维平面上十字叉丝的偏移量x,y来表征光轴间竖直角β′和水平角α′。建立数学模型找出上述变量的关系,并且搭建实验,通过实验数据验证此关系的正确性,同时验证该多轴一致性测量方法的可行性。实验数据显示光轴夹角总误差小于12″,符合系统指标,同时说明该测量方法真实、有效。

To enable the text of Multi-axis Parallelism, a wide-spectrum and multi-axis parallelism test Cassegrain system is designed. Aiming at this system,A texting scheme which use two theodolite auxiliary coordination is put forward,Establish mathematical model to analyze the test method,Derive the relationship between vertical and horizontal angle between the optical axis and displacement distance x,yof collimator reticle. Contrast theoretical analysis and experimental result,The maximum deviation of the value is less than 12＂ within the experimental accuracy range. Verify the feasibility of the method.
