Abstract

An analysis, based on mode coupled equation, is presented of polarization effects in the Sagnac interferometer sensor for distributed detection. The Sagnac distributed disturbance location sensor with polarization controller is established. With a modified demodulation method, experiment results show the system's sensitivity can be improved effectively.
