Abstract :
In order to ensure Avalanche Photodiode (APD) in its optimal state in Laser Gyro when temperature varies, the effect of temperature on avalanche gain is analyzed based on APD´s multiplication principle, a mathematical model of false alarm ratio (FAR) and multiplication factor of APD has been established, and an actual temperature coefficient of breakdown voltage of the device is obtained by monitoring FAR for avalanche noise. The stability of APD´s gain can be enhanced by temperature compensation according to actual temperature coefficient.
