在光学生产中多年来一直运用参考文献[1]中叙述的自准法,于棱镜镀膜之前(不产生内部全反射)检验角度误差。检验时还利用一种专门的反射装置,它以其三个球面支掌点贴附到棱镜上。本文论述此种检验法在实际应用方面的一些特点、测量误差源和实验研究的结果。对参考文献[1]中出示的两个公式(1)和(2)进行分析之后指出,棱镜出射光束方向误差б(?)和б(?)是由反射装置各镜面的平行差θκ造成的,它可在棱镜的主截面和垂直面内测定,当θ_k改变符号时,方向
In optical production, the self-alignment method described in Ref. [1] has been used for many years to verify the angular error before prism coating (without generating total internal reflection). Inspection also uses a special reflector, which with its three spherical support points attached to the prism. This article discusses some of the characteristics of this test method in practical applications, measurement error sources and experimental results. After analyzing the two equations (1) and (2) shown in Ref. [1], it is pointed out that the direction error б (?) And б (?) Of the prism exit beam are caused by the parallel difference θκ of the mirror surfaces of the reflecting means , Which can be measured in the main cross-section and the vertical plane of the prism. When θ_k changes the sign, the direction
