摘要

莫尔条纹的电子学细分需要有一对光电正交的莫尔条纹信号。本文叙述了在圆光栅系统中产生裂相误差的四种原因和消除它们的办法。最后

在一台圆分度检验仪上已经得出了优于0.5°裂相误差的结果。

Abstract

A pair of photo-electric orthogonal Moir? fringes is necessary for the electronic interpalotion of Moir? fringe signals.This paper describes four ki-nds of reasons leading to separated-phase error and the methods of elimina-ting these separated-phase error.A result with separated-phase error less than 0.5癶as been obtained in a circular dividing calibrating instrument.
