Abstract

The results of study of a fiber-optic gyroscope prototype with 0.01–0.001deg/h drift are presented. The gyroscope comprises three feedback loops: one for Sagnac phase difference compensation, the second one for the scale factor stabilization, and the third (fast-response) one for the compensation of constant component of optical signal on the photodetector, affecting the measurement channel. To increase the accuracy of the prototype gyroscope up to the level of 0.001 deg/h, it is proposed to use the fourth and the fifth feedback loops which will suppress the parasitic effects in the integrated optic phase modulators.

通过抑制集成光学相位调制器中的寄生效应来提高光纤陀螺仪的精度

摘要

给出了具有0.01–0.001deg / h漂移的光纤陀螺仪原型的研究结果。陀螺仪包括三个反馈回路：一个用于Sagnac相差补偿，第二个用于比例因子稳定化，第三个（快速响应）用于补偿光检测器上影响测量通道的光信号的恒定分量。为了将原型陀螺仪的精度提高到0.001度/小时的水平，建议使用第四和第五反馈环路，这将抑制集成光学相位调制器中的寄生效应。
