【摘要】：硅雪崩光电二极管(Si-APD)的雪崩电压对温度极大地限制了基于Si-APD的单光子探测器在全天候野外条件下的实际应用。提出了一种可以在大环境温度变化范围内稳定工作的Si-APD单光子探测技术。通过制冷与数字偏压补偿相结合的技术,自动补偿Si-APD的工作温度漂移,保持稳定的雪崩增益。实验证明在-40~45℃的温度范围内采用该技术的单光子探测器工作稳定。实验结果表明采用温漂自动补偿的技术后,Si-APD单光子探测器具备了在温度变化较大的外场稳定运行的能力,为机载或星载光子计数激光测量提供了高稳定性的单光子探测技术。
[Abstract]:The avalanche voltage of silicon avalanche photodiode (Si-APD) greatly limits the practical application of single-photon detector based on Si-APD in all-weather field conditions. In this paper, a Si-APD single photon detection technique, which can work stably in large ambient temperature range, is proposed. Through the combination of refrigeration and digital bias compensation, the temperature drift of Si-APD can be compensated automatically, and the avalanche gain can be maintained. The experimental results show that the single photon detector using this technique is stable in the temperature range of -40 鈩，
