| 摘 要： | 本文通过最佳信号噪声比分析，讨论了单分子辐射单光子在具有时间均匀分布背景信号时对同步取样时间的选取。利用理论分析单分子光子源最佳信噪比与取样门的对应关系，应用计算机虚拟取样测量单分子光辐射信号，有效地抑制了背景信号的影响，分析了光场的光子统计分布特性．

| Abstract: | We theoretically discussed the synchronization sample gate time determination by considering the optimal Signal-to-Noise Ratio (SNR) where the background showed time-uniformity distribution. Computer-based virtual sampling with the appropriate gate time decided for the single- molecular photons timestamps was processed. In this way, the effect from background was greatly reduced, and the photon statistics distribution was analyzed efficiently. |
