摘要
为避免传统光强差稳频方式的缺陷,提出了四频差动激光陀螺小抖动稳频方法。从四频陀螺工作原理出发,分析了小抖动稳频的可行性,其中工作模式判别问题是技术难点。提出三种解决方法:改变左右旋模频率间隔、光强差稳频方式的扫模电路结合、根据陀螺零漂数据来判别,为进一步研究提供了参考。
In order to avoid the drawbacks of light intensity difference frequency stabilization (LIDFS), the dithering frequency stabilization (DFS) for four frequency differential laser gyro (FFDLG) is put forward. Based on the operating principle of FFDLG, the feasibility of DFS are analyzed. Distinguishing the operation modes is the key technological problem. Three solutions are presented : changing the mode frequency space of the left and right circularly polarized, associating with the mode searching circuits of LIDFS ,judging by the null shift data of gyro, which will be helpful to the further study.
