Abstract

Huge enlargement of the sensing range of Brillouin optical correlation domain analysis (BOCDA) is achieved by simultaneously applying double modulation and optical time gate on the basis of differential measurement scheme. The BOCDA system with a spatial resolution less than 1 cm and a sensing range over 10 km is experimentally demonstrated, which corresponds to distributed measurement with more than 1 million effective sensing points.
