摘　　要： 主要针对在点对点的光无线通信系统基础上组建而成的光无线局域网,具体描述了应用于光无线局域网的光无线通信系统的组成和原理,主要包括通信系统的光源的选择、发射电路的设计、接收光电二极管的选择、接收电路的设计以及发射和接收天线的选择。这种设计具有可靠性、数据传输速率高、成本低、抗电磁干扰能力和抗衰弱能力强、带宽高、器件尺寸小等优点。 In the paper, the configuration and principle of the optical wireless communication system which is applied to Optical Wireless Local Area Nctwork （OWLAN） based on point to point are described in detail,mainly including the selection of light source,the design of emitted circuit,the selection of receiving photoelectric diode,the design of receiving circuit and choice of emissive antenna and receiving one. The design is used for its high reliability, quick data transmission speed,lower cost ,good performance on resisting electromagnetic interference and enervation, wide bandwidth, small size of every part in system and so on.
