Paper Abstract

This paper proposed a calibration scheme of optical path correlator(OPC) for optical coherence domain polarimeter (OCDP), the calibration scheme employs a dual Mach-Zehnder interferometers multiplexing one OPC by dual wavelength wave division multiplexer, one interferometer as target interferometer is used to sensing measurement, another interferometer with 3×3 coupler as reference interferometer is used for OPC scan speed and positon calibration to improve the target interferometer signal-to-noise ratio(SNR) and interference envelope positioning accuracy, this calibration scheme is used OCDP to measure polarization crosstalk, the experimental results show that SNR is achieved 95dB and the polarization crosstalk position accuracy is achieved submicron.
