一种光子探测方法及装置
摘要：
本申请揭示了一种光子探测方法及装置。该方法主要包括：S1，调整单元调整探测单元的偏置电压以开启探测单元；S2，在探测单元探测到光子并发生雪崩倍增效应之后，淬灭单元控制探测单元中的电荷堆积以淬灭探测单元的雪崩倍增效应，并且控制探测单元中堆积后的电荷释放以恢复探测单元对光子的探测能力；S3，计数单元对探测单元在电荷堆积和释放的过程中产生的电信号进行计数；S4，读取单元在第一预设时间内读取计数单元所记录的计数数据，并且同时调整单元调整探测单元的偏置电压以关闭探测单元；S5，重复S1-S4，直到完成预设时钟周期内的光子探测。通过本申请公开的技术方案，可以提高光子探测的动态范围和光子探测灵敏度。
摘要（英）：

The invention discloses a photon detection method and a device. The method mainly comprises the steps of: S1, an adjusting unit adjusting the bias voltage of a detection unit to turn on the detectionunit; S2, after a photon is detected by the detection unit and occurrence of an avalanche multiplication effect, a quenching unit controlling charges in the detection unit to accumulate so as to quench the avalanche multiplication effect of the detection unit, and controlling the accumulated charges to be released in the detection unit to recover the photon detection ability of the detection unit;S3, a counting unit counting electric signals generated by the detection unit in the process of accumulating and releasing the charges; S4, a reading unit reading the counting data recorded by the counting unit in a first preset time, and meanwhile an adjusting unit adjusting the bias voltage of the detection unit to close the detection unit; and S5, repeating the steps S1 to S4 until the photondetection in a preset clock cycle is completed. According to the technical scheme disclosed by the invention, the dynamic range and photon detection sensitivity of photon detection can be improved.
