Эффективный метод алгоритмической коррекции дрейфов зеемановского лазерного гироскопа

Ладонкина М. В., Колбас Ю., Соловьева Т. И.

The laser gyros operating in wide temperature range need in the effective correction of the drift. The paper is devoted to the investigation of the physical reasons of time and temperature drifts of Zeeman laser gyro with periodic realignment of the laser longitudinal generation mode with the light wave opposite circular polarization. It is designated that gyro drift can be divided into magnetic and non-magnetic components having different nature and provides significantly different contribution to the final error. The expression of total error depending on the gyro operation mode is presented. The reasons of magnetic and non-magnetic drifts are described and optimal algorithmic methods of their compensation are proposed both with initial calibration and without it. Experimental results for several Zeeman laser gyroscopes with drifts typical values are analyzed.
