本文探讨利用偏振辐射特性的光电测角仪一偏振测角仪。这类测角仪的优点是:关于被测角(也包括扭转角)的信息,均包含在光辐射偏振状态之中,这就可以建立光路直径小于其它型号测角仪的装置。根据调制方法,已知有下列型号的偏振测
This article discusses the use of polarization radiation characteristics of the goniometer-polarization goniometer. The advantage of such a goniometer is that the information about the measured angle (also including the twist angle) is included in the polarized state of the optical radiation, which makes it possible to establish a device with a smaller optical path than the other goniometers. According to the modulation method, the following types of polarizations are known
