Abstract
We propose a novel scheme of optical pulse compression reflectometry (OPCR) based on double sideband modulation (DSBM). Owing to the use of DSBM in the novel scheme, the cost-effectiveness and the stability of the OPCR are essentially enhanced. The working principle and the theoretical analysis are demonstrated. Experiment is conducted to verify that the performance of the DSBM-based OPCR is comparable with that based on single sideband modulation. Large measurement range over 58 km with high spatial resolution of 10 cm is experimentally achieved.
