摘要
针对硅单光子雪崩探测器探测效率高准确度测量的需要,建立了一套溯源至标准探测器的硅单光子探测器探测效率测量装置.首先通过大动态范围高精度衰减产生光子数已知的准单光子源来校准探测器的探测效率,其次对影响探测效率测量的后脉冲概率和死时间进行了分析与测量,最后系统分析了各测量不确定度的来源,实现了硅单光子雪崩探测器在632.8nm波长处探测效率测量不确定度达到0.6%(k=2).该装置采用超连续谱光源与单色仪组合输出单色光源,结合标准探测器,可根据需要实现硅单光子雪崩探测器宽波段内的探测效率自动化测量.
An experimental facility designed for the detection efficiency mesaurement of silicon single-photon avalanche detector traceable using standard detector is described.The photon rate is determined from the standard detector and a large dynamic range attenuation technique.Furthermore,the afterpulsing probability and dead time are considered and meaured.The component uncertainties associated with the measurement of detection efficiency are analyzed.The obtained expanded measurement uncertainty is 0.6%(k=2).Combining the monochromatic source consisted of supercontinuum laser and monochromator,the detection efficiency of silicon single-photon avalanche photodiodes could be automatic measured in a broad wavelength range using the standard detector in the setup.
