摘要
动态测角应用广泛，技术难度大。应用环形激光传感器（ＲＬＳ）设计成功的动态测角系统，具有精度高，测量快，结构简单，操作方便等优点。ＲＬＳ输出信号作速度反馈，控制系统控制转台恒速转动，光学指零传感器将反射光束转换成电脉冲，控制计数器工作，通过多次重复测量和计算机数据处理，使重复测量精度达到±０．２ａｒｃｓｅｃ。
Dynamic angle measuring system has various utilities, and its technology is hard to realize. The dynamic angle measuring system using ring laser sensor (RLS) shows many advantages such as high accuracy, high speed, simple structure and easiness of operation, etc. We used output of RLS as the velocity feedback. The control system controls the table to rotate at a constant speed. Optical zero pointing sensor converts the reflecting light into electrical impulse to control the counter. Through many times of measurement and data processing in the computer, the repeated measurement accuracy reaches ±0.2 arcsec.
