Abstract

Frequency response of a laser gyroscope was studied by numerical modeling of a complete system of equations describing it. The calculation results are compared to the results of experimental measurements taken on a precision dynamic test bench. The frequency response was measured for a gyroscope based on a four-mirror ring laser with a non-planar contour, operating on He–Ne active mix at the wavelength of 632.8 nm. In the gyroscope under study, the sign-variable dither was implemented on the basis of Zeeman magnetooptical effect. The relationship between the measured and designed values of the frequency response distortions has been found. The relationship between the frequency response distortions in a laser gyroscope and inequality of field intensities of the counter-propagating waves (CPW) has been numerically calculated and confirmed by experiments. Based on the research results, the parameters of a ring laser can be optimized to improve the accuracy of measurements by means of laser gyroscopes.

反向传播波强度不等对激光陀螺仪频率响应的影响

摘要

激光陀螺仪的频率响应是通过描述该方程的完整方程组的数值模型研究的。将计算结果与在精密动态测试台上进行的实验测量结果进行比较。对于基于非平面轮廓的四镜环形激光器的陀螺仪，在He-Ne活性混合物上以632.8 nm的波长进行操作，测量了频率响应。在所研究的陀螺仪中，基于塞曼磁光效应来实现符号可变抖动。已经找到了频率响应失真的测量值与设计值之间的关系。激光陀螺仪中的频率响应失真与反向传播波（CPW）的场强不均之间的关系已通过数值计算并通过实验得到证实。根据研究结果，可以优化环形激光器的参数，以提高通过激光陀螺仪进行测量的准确性。
