本文描述一种基于CCD平均能量法使光学边沿对准的光电测量方法。该方法采用光栅作计量元件，精密平合作扫描方式，实现了自动高精度的光学码道测量．特别适用于卫星定向用的光学码盘码道尺寸精密测量。
This paper describes a photoelectric measurement method based on the CCD average energy method to align optical edges. The method uses a grating as a measuring element and a precision flat cooperation scanning method to realize automatic and high-precision optical code track measurement. Especially suitable for satellite-oriented optical code track size precision measurement.
