The Compensation Methods of the Start-up Drift of Four Frequency Differential Laser Gyro

摘要：

The start-up drift of four frequency differential laser gyro is of great importance in the fast launching occasions like missiles and fighter plane. This paper studies the characteristics of startup drift and presents two kinds of compensation methods. Based on the tradihonal mathematic model in terms of temperature, temperature changing rate and temperature gradient, the software compensation is done with the drift data. From the analysis of the physics mechanism of start-up drift, the hardware compensation is realized by adopting the corresponding technologies to control the specific physics parameters thermal changes which directly cause the start-up drift. Experiments show that software compensarion is of little use while hardware compensation is more suitable and effective.
