基于光电混合振荡的随机数生成装置
By generating random numbers through a photoelectric hybrid oscillation system, the high cost of hardware random number generators and the insufficient security of pseudo-random number generators in existing technologies are solved. This achieves high randomness and high output rate of random number generation, with extremely strong security and reliability.

Abstract
一种基于光电混合振荡的随机数生成装置，包括：光脉冲信号产生模块，用于产生光脉冲信号；第二调制器件，用于将反馈信号调制到光脉冲信号上，产生第二光脉冲信号；微波频率源，用于产生微波本振信号；信号反馈模块，用于将第二光脉冲信号转化为第二电脉冲信号，并将第二电脉冲信号与微波本振信号混频后得到反馈信号；其中，第二调制器件与信号反馈模块形成光电混合振荡系统，微波本振信号将光电混合振荡系统中的第二光脉冲信号相位等概率的锁定为0或π，光脉冲信号控制光电混合振荡系统高速开关得到相位0或π随机出现的光脉冲信号，即随机脉冲信号。本装置结构简单，可产生高随机性随机数列，具有极强的安全性和可靠性。
