Abstract

An electro-optical common path architecture based on the generation of orthogonal polarization dual frequency comb is used in time-expanded phase-sensitive-OTDR. An enhanced temporal stability and a reduction of the transmitter complexity are achieved while maintaining the performance in resolution.
