[00119569]单码道绝对位置的编码方法及读数测量系统

一种单码道绝对位置的编码方法及读数测量系统,该绝对位置编码方法的编码空间是编码条纹的频率空间,用条纹的空间分布频率记载编码信息。该编码方法能够大大削弱读数时对单个编码位信息完整性的依赖。本发明同时提供一种适配本编码方法的读数测量系统。该系统编码译码程序简单快速;局部可细分,微位移分辨率高;码道制造难度小,工序简单。 | The invention discloses a single code channel absolute position coding method and a reading measuring system. According to the absolute position coding method, coding space is coded strip frequency space, and coding information is recorded by spatial distribution frequency of strips. By the coding method, dependence on single code bit information integrity during reading can be greatly weakened. The invention also provides a reading measuring system for the coding method. The system has simple and rapid coding and decoding programs; local subdivision can be realized and micrometric displacement resolution is high; and difficulty in manufacturing code channels is low, and processes are simple。
