四频差动激光陀螺色散补偿技术研究

Dispersion compensation of four-frequency differential laser gyroscope

通过对四频差动激光陀螺增益介质色散效应的影响分析，提出补偿方法抑制反常色散效应对激光陀螺零偏的影响。通过色散补偿方案，可明显抑制四频差动激光陀螺的零偏漂移误差，为高精度四频差动激光陀螺的设计提供一种重要的技术方案。

By analysing the dispersion effect in four-frequency differential laser gyros, the methods and means for compensating the bias by dispersion effect was given here. The dispersion compensation method could obviously restrain bias drift and afford an important technical method for design of high accuracy four-frequency differential laser gyro.
