摘　　要：本文对光纤陀螺系统中Y波导相位调制器的直流相位漂移参数进行研究分析,搭建了一套全自动测试系统,在实现对Y波导处于常温下准确测试的基础上,首次实现全温下(−40℃~+85℃)直流相位漂移参数一键式自动化测试。结果表明:搭建的测试系统能够连续、快速地对Y波导的直流相位漂移参数进行测试,在常温下直流相位漂移参数的标准差小于72 ppm,在全温下直流相位漂移波动幅度在3.06‰以内,全温状态下直流相位漂移参数具有重复性。In this paper, the DC phase driftparameters of Y-waveguide phase modulator in fog system are studied andanalyzed, and a set of automatic test system is built. Based on the accuratetest of Y-waveguide at room temperature, the one click automatic test of DCphase drift parameters at full temperature (−40˚C~85˚C) is realized for the first time. Theresults show that the test system can continuously and quickly test the DCphase drift parameters of Y-waveguide, the standard deviation of DC phase driftparameters is less than 72 ppm at room temperature, the fluctuation amplitudeof DC phase drift is less than 3.06‰ at full temperature, and the DC phasedrift parameters have repeatability at full temperature.
