The paper discusses a new method that combines frequency and phase domains-gated reflectometry. This approach can be applied to a fiber with artificial reflectors to measure the absolute values of optical paths between reflection points in the fiber in the full range of signal frequencies, including zero frequency.

基于具有反射点的光纤的频域和相域时控反射镜组合，可进行绝对测量

本文讨论了一种结合频域和相位域门控反射法的新方法。该方法可以应用于带有人工反射器的光纤，以在整个信号频率范围（包括零频率）中测量光纤反射点之间的光路绝对值。
