基于使用细长临界角棱镜的内反射效应的角度测量。

Appl Opt. 1996 May 1;35(13):2239-41. doi: 10.1364/AO.35.002239.

Elongated critical-angle prisms that provide multiple reflections have been used to increase measurement sensitivity while retaining excellent linearity in the recently developed angle-measurement method, angle measurement based on the internal-reflection effect.

在最近开发的角度测量方法（基于内反射效应的角度测量）中，提供多次反射的细长临界角棱镜已被用于提高测量灵敏度，同时保持出色的线性度。
