应用圆栅云纹偏折技术确定光束的方向

Beam Direction Determination by moire Deflectometry Using Circular Grating

本文应用圆栅云纹的偏折技术,确定光束的方向,测量平板玻璃的楔角,该方法亦可用于自准直平行光管,方法简单,测量迅速,灵敏。

The poaper presents a simple, fast and sensitive method, which is based on the use of moire deflectometry of circular grating to determinate beam direction and to measure wedge angle of plate glass. The method is used as an autocollimator.
