Simulations on light intensity are validated by experiments and influence of mechanical dither on gyro frequency stabilization is studied for the first time . then it is point out that the key to improve the precision of frequency stabilization is to choose appropriate modulation frequency based on the frequency spectrum of sharp pulses , which is introduced by mechanical dither . thereafter , experiments of frequency stabilization under different modulation frequencies are made
通过实验验证了光强仿真结果，首次分析了机械抖动对稳频的影响，指出提高机抖陀螺小抖动稳频精度的关键在于：根据机械抖动引入的交流光强尖峰脉冲频谱分布选择合适的调制频率，并给出了不同调制频率的稳频实验结果。
Secondly , considering the need of frequency stabilization , mdrlg ' s light intensity is simulated . the simulations indicate that sharp pulses are produced in the ac light intensity by mechanical dither . as the pulses have a wide frequency spectrum and range over the modulation frequencies of frequency stabilization , mechanical dither may reduce the precision of frequency stabilization
其次，根据稳频需要对机抖陀螺输出光强进行了仿真，仿真表明机械抖动会在交流光强中引入尖峰脉冲，且尖峰脉冲频谱分布较宽，在小抖动稳频调制频率范围内有功率输出，因而可能降低稳频精度。
