摘　　要：用于航摄测量,大地测量和星体测量等方面的精密光学仪器,在出厂前必须进行完整地校准和检验,以便确定它们的焦距、畸变量,并且在允许的范围之内给出畸变量的修正值。本文介绍了利用高精度光学经纬仪来测量跟踪电视光学系统的焦距和畸变,并对测量精度进行了分析。指出了测量中需要注意的几个主要问题。The fine optical instruments used for aerial photographic survey, geodetic survey and celestial body survey and so on must be calibrated and checked completely before leavinng the factory, so as to determine their focal lengths and distortions, and give out corrected values of distortions in permissible range. The paper deals with focal length and distortion of TV optical system determ ined by the high-precision theodolite, and analyzes measuring accuracy, and it puts forward a few principal problems to be noticed.
