Abstract

We propose a phase shift pulse BOTDR (PSP-BOTDR) using probes composed of long and short pulses with phase shift keying modulation, and evaluate its performance by experiment and simulation. Modifying the previous probe configuration reduces signal leakage from the adjacent section to a negligible extent, and achieves truely a spatial resolution of 20 cm.
