查询词典 retardation

The measurement beam travel through the half circular polariscope and rotating analyzer to generate a measurement signal. As these two signals are guided into the lock-in amplifier, the phase retardation of the waveplate can be obtained.

由於锁相放大器所显示的相位延迟量在-180°~180°范围内，超出此范围则会产生误判，因此加入波长位移的技术，透过波长改变前后所产生的相位延迟量变化差值，可由此差值之正负号确定波板慢轴方向。

This thesis arms to develop a measurement system for detecting phase retardation, slow axis orientation, and optical path difference of a waveplate. The structure of the system includes three laser light source, a half circular polariscope, a rotating analyzer, an optical chopper and a lock-in amplifier.
