摘要

本文研究了二频和四频塞曼激光陀螺仪中由辐射散射引起的反传播波耦合对其特性的影响。提出了通过确定反传播波的调幅参数和通过重建拍频信号相位来测量反传播波耦合强度的方法。利用得到的耦合幅度值，通过对陀螺仪腔体进行几何调整，使耦合幅度减小2 ~ 7倍。对双频和四频激光陀螺仪在不同反传播波耦合量级下的零点漂移和其他参数进行了测量。

Coupling of Counterpropagating Waves in Two-and Four-Frequency Zeeman Laser Gyroscopes with a Nonplanar Cavity

The paper considers the effect of coupling of counterpropagating waves caused by scattering of radiation in two- and four-frequency Zeeman laser gyroscopes on their characteristics. Methods for measuring the magnitude of coupling of counterpropagating waves via determination of parameters of the amplitude modulation of counterpropagating waves and via reconstruction of the beat signal phase are presented. The obtained values of the coupling magnitude were used to minimize it by 2–7 times by the geometry adjustment of the gyroscope cavity. Measurements of the zero drift and other parameters of two-frequency and four-frequency laser gyroscopes at different coupling magnitudes of counterpropagating waves have been carried out.
