Paper Abstract

Measurement range enhancement technique is proposed for distributed sensing of optical frequency domain reflectometry (OFDR) system. By using quadrature detection method in detection part, measurement range can be two times extended compared to conventional OFDR. Distributed strain sensing capability is experimentally reported with extended range up to full coherence length of tunable laser source by analyzing Rayleigh back-scattering signal obtained from the proposed quadrature detection of OFDR system.
