摘要：

为实现基于相关光子的光电探测器在连续宽波段量子效率定标，研究相关光子光谱和速率分布具有重要意义。通过理论模拟相关光子光谱和速率分布规律，建立了连续宽波段相关光子光谱和速率分布测量实验系统，利用该系统测量了450~700 nm连续宽波段相关光子的光谱和速率分布，将实验测量的光子速率分布与理论模拟结果进行比较，两者曲线形状相关系数为99.39%，表现出高度的一致性。实验结果表明：相关光子具有连续宽波段光谱分布，有望为实现基于相关光子的光电探测器在连续谱量子效率定标提供理论依据和实验指导。

Abstract:

In order to realize the calibration of photoelectric detector at continuous and broad-band based on correlated photon, it is necessary to investigate distribution of the correlated photon spectra and photon count rate. By simulating distribution rule of the correlated photon spectra and photon count rate, an experimental system is set up to measure the spectra distribution and the photon count rate distribution of continuous and broad-band correlated photon. The spectra distribution and the photon count rate during 450~710 nm are measured by using the system. Strict consistency is revealed by comparing theory simulation result with experimental ones, and the correlated coefficient is 99.39%. The results shows that correlated photon have continuous and broad-band range. It can be applied to direct the calibration of quantum efficiency of photoelectric detector at continuous based on correlated photon in theory and experiment.

Key words: correlated photon, spectra distribution, photon count rate, continuous and broad-band
