摘　　要：对一种可用于楼宇之间或校园环境的近距无线光信息加密传送的方案进行了简要讨论。设计的系统中采用可见光作为工作波长,液晶屏为调制器,凸透镜系统为发射、接收光学天线。提出简易色度矢量替代型仿量子密钥的设计方法并对其性能进行了分析。然后在不同的传输条件下,不断进行室外测试试验,从而验证系统模型的可靠性。实验表明,该系统可实现短距离的加密光通信并可作为模仿量子通信的示教工具。Used between buildings and in the school environment, the paper briefly describes the program of short-range wireless optical information encrypted transmission. The system used as a working wavelength of visible light, I.CD screen for modulators, convex lens system for launch optical antenna and receive optical antenna. It detailedly describes the design methodology of chroma vector substitute which simulating quantum key distribution, especially discuss the capability in this condition. According to different transmission conditions, the ongoing testing experiments outdoor which verify the reliability of system models. Experiment show on which encrypted optical communication in short-haul can be achieved. And as a teaching tool for simulation of quantum communication.
