摘要
介绍了保偏光纤拍长测量的几种常用方法,就其测量原理,试验装置及优缺点分别进行了较为详细的分析和说明。并就目前多数测量方法适用于高双折射光纤的不足,介绍了一种较好的测量低双折射光纤拍长的方法。
Several beat length measuring methods for polarization maintaining fiber were introduced, according to which the test principles, experimental installations, merits and faults were analyzed and compared in detail. Also a better method for measuring low-birefringence fiber was introduced owing to the deficiency of the present methods which are mostly fitted for high-birefi＇ingence fiber.
