摘要

在圆光栅用于角度基准研究中采用莫尔条纹的电载波调制电细分

把一对正交的莫尔条纹信号分成20000等分

并可实现仪器的动态和静态测量

还能动态检测光学度盘和圆光栅

Abstract

Carrier modulated interpolation of Moire fringes is applied to the study of angle standard with radial gratings

which has divided the orthogonal Moire fringes signal into 20000 parts.The interpolation has achieved dynamic and static measurement.It can also dynamically measure the optical circular divided scales and radial gratings.
