Abstract

An effect method for reducing the birefringence dispersion in Optical Coherence Domain Polarization (OCDP) is proposed in this paper. Based on an all-fiber OCDP system with a reversing mechanism before the polarization maintenance fibers (PMF), wide spectrum of light was launched into the testing PMF in the clockwise direction and counter-clockwise direction and we obtained the measurements of symmetrical two polarization-coupling. By processing the measurements, we reduced the length of the testing fiber to a half equivalently. The experimental results show that the amplitude resolution of polarized coupling in all-fiber OCDP system is -84dB, the dynamic range of measurement is 84dB and the spatial resolution is 49.3mm without the dispersion in PMFs. By this method, the measurement accuracy of the coupled position and amplitude in PMFs was enhanced, and the effects of birefringence dispersion were inhibited.
