| 摘 要： | 为保证激光陀螺中雪崩光电二极管(APD)在温度变化的情况下始终处于最佳工作状态,从APD的倍增机理出发,分析了温度对雪崩增益的影响,建立了虚警率与APD倍增因子的数学模型,并采用监测雪崩噪声平均过阈率的方法,得到器件的实际击穿电压温度系数γ=6.088×10-3/℃,按实测γ进行温度补偿,有利于提高APD增益的稳定性。

| Abstract: | In order to ensure the optimum operating of the avalanche photodiode(APD) in the laser gyro under different temperature conditions,an effect of the temperature on the avalanche gain is analyzed based on the principle of APD multiplication.A mathematic model of the false alarm ratio(FAR) and the multiplication factor of APD is established.The obtained reality temperature coefficient of breakdown voltage of the device is 6.088×10-3 /℃ by monitoring FAR for avalanche noise.The compensation according to the actual temperature coefficient is advantageous to enhance the stability of the APD gain. |
