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。The avalanche voltage of the Si avalanche photodiode （Si-APD） is temperature sensitive, which greatly limits the practical application of the single-photon detector based on Si-APD for the all-weather operation in field. A technology is developed to guarantee stable working of the Si-APD single-photon detector with a wide-range environmental temperature tolerance. The digital bias voltage auto-compensation technique is combined with the refrigeration, which can automatically compensate the operation temperature drift and maintain a stable avalanche gain of the Si-APD. The experiment proves that the single-photon detector with this technology can work stably in the temperature range from -40 ℃ to 45 ℃. The experimental result indicates that by using the proposed auto- compensation technique, the Si-APD single-photon detector has the ability of stable working in the outfield with great change of temperature. The single-photon detection technology with high stability can be provided for the photon counting laser measurement of the airborne and satellite-borne.
