Abstract
We present a novel approach for incoherent optical frequency-domain reflectometry based on a frequency-swept sinusoidal optical signal and a Kerr phase-interrogator. The novel approach eliminates dependence on the laser coherence-length allowing for long-range operation. Long-range detection of reflection points as far as 151 km at a spatial-resolution of 11.2 cm is experimentally demonstrated.
摘要
我们提出了一种基于扫频正弦光信号和克尔相位询问器的非相干光频域反射测量新方法。该新方法消除了对激光相干长度的依赖，从而实现远距离操作。实验证明了在空间分辨率为11.2厘米的情况下，能够对距离达151千米的反射点进行远距离检测。
