激光陀螺稳频测试技术研究

本文研究了机抖激光陀螺稳频系统性能测试的两种新方法：压电扫频和光强扫频。通过两种方法实现对稳频抓卡系统进行动、静态测试，描绘出稳频系统在工作频率段（5KHz~18KHz）范围内的谐振峰特性曲线。试验结果表明，两种方法，尤其是光强扫频，更具有实际操作性，有助于稳频电路调试参数的选择，从而有效的避开谐振峰，提高激光陀螺工作的稳定性及环境适应性，也为稳频系统电路设计提供了改进方向和依据。

Testing Technology for Laser Gyroscope Frequency Stability

Two kinds of new methods which is used to test the performance of frequency stabilization system for the mechanically dithered laser gyroscope is studied in this paper: PZT and light intensity frequency scan. Through dynamic and static testing of the length control system, we find out the frequency characteristic curves of resonance peak within the operating frequency (5kHz-18kHz). The experiment indicates that the two methods above, especially light intensity frequency scan, are all actual practical and contribute to selection of debugging parameter for frequency stabilization circuit. The two methods also effectively avoid the resonance peaks, improve the stabilization and environmental suitability of laser gyroscope, and provide the better direction and basis for circuit design of length control system.
