Using phasemeter, the two prisms can be moved out off the beam, so the system can be used to measure coaxality. 对测量信号的处理，采用比相技术，测量元件可以暂时移出光路，因而能够进行同轴度的测量。
In this paper, a new method for solving the erratic area in the phasemeter, it is based on 401-Model Automatic Polariscop system. 本文以401型自动光弹仪的测试系统为例,对相位比较器中存在的“盲区”问题,提出并实现了一种新的自动处理方法。
Digital phasemeter based on virtual instrument technology 基于虚拟仪器技术的数字相位计
Influence of frequency and wave distortion on the verification of phasemeter 频率和波形失真度变化在相位表检定中的影响
