Dual-comb OFDR system for high-precision distributed fiber sensing
Optical Frequency Domain Reflectometry (OFDR) is a distributed optical fiber sensing technique based on frequency domain analysis. In this work, we propose an OFDR based on dual comb system that replaces the conventional tunable laser source in the OFDR system with dual optical frequency combs based on external modulation, which enables sub-nε/√ Hz detection sensitivity limit.
