Abstract

We present several advanced techniques for evaluating the quality of fiber gyro coils, including characterizing the temperature and vibration transient characteristics of fiber coils, monitoring polarization-maintaining fiber (PMF) coil winding quality using distributed polarization crosstalk analyzer (DPXA) during production, and the defect detection of fiber coil using optical coherence tomography (OCT). To the best of authors' knowledge, this is the first report of using OCT for fiber coil inspection. The use of these new techniques can effectively improve and guarantee the quality of the fiber gyro coils.
