本文报道利用λ/4波板和偏振分祈器测量单模光纤双折射率的一种方法.与已有方法比较我们选择了较方便的可测量,并推导了双折射相位延迟与可测量之间的解析公式.本方法也可用于类似条件的光学测试中.

A simple method for polarization measurement using a quarter-wave plate and an analyzer has been described in this paper. In the experiments a more convenient sot of measurable quantities was chosen and an analytical solution from a set of equations which are for determing linear retardation in fiber was obtained. Using this solution the measurements and calculations become quite simple. The measurement errors can be determined from this explicit formula also.
