摘要
对光纤陀螺中SLD光谱调制度的变化进行了实验研究.从理论上阐述了光路系统中光谱的调制度增大的原因,其仿真与实验结果非常一致·在此基础上,进一步分析了光谱调制度对相干函数的影响,评估了二阶相干峰引起的光纤陀螺误差水平·
The changes of SLD＇s spectral modulation in fiber-optic gyroscope was studied with experiment, the reason for the increasing of spectral modulation depth through the whole optical path was explained in theory, and the emulation result was highly consistent with the experimental result. On the basis of that, the influence of spectral modulation on the coherence function was analyzed, and the error level of fiber- optic gyroscope which arise from secondary coherence peak was evaluated.
