This paper presents a new way to measure the characteristic parameter of the phase shifting controller made of fiber with PZT by phase shifting.
提出了一种利用相移技术测定光纤PZT相移控制器相移特性参数的方法。
The method is phase shifting with any four steps in a facultative interval, and in combination with grouping disposal the parameter is got.
