A simple theoretical description of coupling phenomena in a laser gyro has been developed. In particular, this allows the calculation of the residual nonlinearity of the response of the laser gyro in the presence of a periodic bias. A laser gyro has been constructed in a CER-VIT block. To solve the lock-in zone problem this detector contains a periodic bias system using the Faraday effect. The results of a number of trials are reported. In particular, we obtain experimental values of residual error due to coupling phenomena for each rotational speed. These results are in good agreement with a simple coupled oscillators theory.
已经建立了激光陀螺仪中耦合现象的简单理论描述。特别地，这使得能够计算存在周期性偏置时激光陀螺仪响应的残余非线性。一个激光陀螺仪已被构建在一个铈钛酸铅（CER-VIT）块中。为了解决锁定区问题，该探测器包含一个利用法拉第效应的周期性偏置系统。报告了许多试验的结果。特别地，我们获得了每个转速下由于耦合现象导致的残余误差的实验值。这些结果与一个简单的耦合振荡器理论高度吻合。
