准平行光远距离动态重合度的自准直测量方法研究

针对野外、远距离、动态的重合度测量要求，提出了一种准平行光自准直测量方法，即发光和接收由一台仪器完成，发出光束为准平行光，反光器件为角锥棱镜，PSD或CCD将反回光转换成电信号，并最终以角度表达重合偏差。通过静态试验验证，证明此方法原理正确，方案可行，测量距离可达公里级，测量结果具有较高的准确度。该方法为实现角度的精确跟踪及专用跟踪仪的研制奠定了基础。

Research on Auto-collimation Measurement of Remote Dynamic Coincidence Degree Based on Quasi-Parallel Light

Aiming at the measurement requirements of wild, remote and dynamic coincidence degree, a sort of auto-collimation method based on quasi-parallel is proposed. Namely light-emitting and receiving are completed by a single instrument, the emanatory light is quasi-parallel light, glisten part is corner cube reflector, PSD or CCD converts the received light to electrical signals, and uses angles to express coinci-dence errors finally. Via static tests, it can be proved that the principle of the method is correct, the scheme is feasible, measure distances can reach up to km level, and the measurement results have a high accuracy. The method provides foundations for accurate tracking angles and development of special tracker.
