摘　　要：该文提出了一种基于偏振态检测技术的利用偏振控制器和光纤偏振器测量径向受力光纤双折射的方法，起偏器和检偏器本身不用旋转而依靠光纤在偏振控制器绕制的半波片使光纤中的偏振态旋转，从而达到在线测量受力光纤双折射的目的。A new method to measure the birefringence of the single-mode fiber which is side-pressed using polarization controller and fiber polarizer is presented based on the technology of polarization state testing. In order to test the birefringence on line, the half-wave plate enwinded by the fiber using polarization controller can rotate the polarization state instead of rotating the polarizers.
