我们为了分析正72面棱体的检定误差,曾对检定棱体时所用的光电自准光管进行了比较全面的检验,本文仅是用激光干涉法测定自准光管测微轮的示值的原理、测定方法等作一简要的叙述。
In order to analyze the verification error of positive 72-sided prism, we have carried out a comparatively comprehensive test on the photoelectric self-used light-guide tube used to test the prism. This article only uses the laser interferometry method to determine the indication of the self- Principle, measurement methods for a brief description.
