摘要

实验研究了四频塞曼激光陀螺仪在具有交变频偏置的正交圆偏振纵向模式下的输出特性，并将其与双频塞曼激光陀螺仪的输出特性进行了比较。结果表明，将四频ZLG表示为一组偏振正交的双频ZLG，可以通过对同一陀螺仪输出特性的算术平均得到四频ZLG的输出特性。介绍了开关频率为1khz的曲流形式的交流偏置四频ZLG的实验输出特性，以及它与频率为1hz的低频曲流的组合。证明了采用慢曲流调制对四频ZLG输出特性进行线性化的有效性。

Output characteristic of four-frequency Zeeman laser gyroscope with an alternating frequency bias

We have experimentally studied the output characteristic of a four-frequency Zeeman laser gyroscope (ZLG) on longitudinal modes with orthogonal circular polarisations having an alternating frequency bias and compared it with the output characteristic of a two-frequency ZLG. It is shown that by representing a four-frequency ZLG as a set of two-frequency ZLGs with orthogonal polarisations, the output characteristic of a four-frequency ZLG can be obtained through the arithmetic mean of the output characteristics of the same gyroscope. The experimental output characteristic of a four-frequency ZLG with an alternating bias in the form of a meander with a switching frequency of 1 kHz, as well as its combination with a low-frequency meander with a frequency of 1 Hz, is presented. The efficiency of using slow meander modulation for the linearization of the output characteristic of a four-frequency ZLG is demonstrated.
