摘要
简要介绍了采用光干涉技术的保偏光纤拍长测量方法,并给出了测量实例。与外调制测量法相比,该方法具有更高的测量重复性,测量原理也更为直观清晰。
The measuring method for beat length of polarization maintaining optical fiber （PMF） using optical interference technique is introduced briefly, and the measurement example is given. The repeatability of this method is better than ＂external modulation＂ method, and its principle of measurement is more visible and clear.
