利用全光纤干涉系统 ,提出了光纤长度测量的新方法 ,与传统的光纤长度测量方法—时域反射 (OTDR)法相比 ,该方法完全消除了OTDR的盲区。通过实验 ,验证了该方法的可靠性和理论分析的正确性。
By using all-fiber interference system, a new method of optical fiber length measurement is proposed. Compared with OTDR method, this method completely eliminates the dead zone of OTDR. Through experiments, the reliability of the method and the correctness of the theoretical analysis are verified.
