介绍了一种手持式、低功耗、时间分辨的单光子探测系统，该系统由一个能够记录10ps分辨率的光波形的时间测量平台和一个检测板组成，该检测板既可以容纳CMOS单光子雪崩二极管(SPAD)，也可以容纳定制的单光子雪崩二极管(SPAD)。它已经在直径高达200μm的CMOSSPAD上得到了验证，在室温下(使用50μm的器件)，在450 nm处达到了40%的光子探测效率，暗计数率低于100 HZ。该系统在半最大单次定时精度下提供50ps的全宽，1.2%的最低有效位差分非线性和160μ的S全量程。数据通信和电源均由USB 2.0链路提供。该模块采用非常紧凑(1×2英寸)的手持式外壳，功耗不到1.3W(即使在最大转换速率为5M/S的情况下也是如此)。由于现场可编程门阵列(现场可编程门阵列)的数据处理，这一完整的时间相关单光子计数系统可以实现定制和经济高效的新应用，这些应用要求高度的便携性和可配置性，而不会影响性能。
We present a handheld, low-power, time-resolved single-photon detection system, consisting of a time measurement platform, able to record optical waveforms with 10 ps resolution and a detection board, which can host both CMOS and custom-made single-photon avalanche diodes (SPADs). It has been validated using up to 200 μm diameter CMOS SPADs, reaching 40% photon detection efficiency at 450 nm and less than 100 HZ dark count rate at room temperature (with a 50 μm device). The system provides 50 ps full-width at half-maximum single-shot timing precision, with 1.2% of least significant bit (LSB) (RMS) differential non-linearity (DNL) and 160 μs fullscale range. Both data communication and power supply are provided by a USB 2.0 link. The module comes in a very compact (1 × 2 in2) handheld housing and consumes less than 1.3 W (even at the maximum rate of 5 Mconversion/s). Because of the field programmable gate array (FPGA) data processing, this complete time-correlated single-photon counting system enables customized and cost-effective new applications, which require high portability and configurability, with no compromises on performance.
