利用光学量子随机源中光子的随机性，设计了一种无需后处理的随机数产生器。在设计中，用弱光源进行单光子水平的探测，利用单光子水平的光源在半导体探测器上一定周期内探测到的脉冲个数服从泊松分布的基本原理，而元器件和读出电子学造成理想泊松分布的变形，通过控制平均计数消除偏差，达到统计学上的无偏。本设计具有自动纠偏功能，产生无后处理的高质量高速真随机数，并通过了NIST、Diehard等多种技术测试标准。

In this article, a random number generator without post-processing, which uses the randomness of photon in optics quantum random source,is designed.The designemploys feeble light to detect at single photon level.The pulse number detected by in fixed period obeys Possion distribution,but effect of electronic compo-nents and readout electronics distortsPossion distribution.Controlling mean count can eliminate bias to achieve unbiased in statistics.High quality and high speed random numbers using automatic bias-correcting technique is producedwithout post-processing and passes all standard tests relevant for random number generators,like NIST,Diehard.
