VLC系统中双面锯齿菲涅尔接收透镜的研究

摘要

To reduce the size of visible light communication (VLC) system,and increase focusing efficiency,this paper designs a new receiving antenna that the Fresnel lens with double-faced tooth based on the traditional VLC receiving antenna that the Fresnel lens with single-faced tooth.The paper shows the design method and simulated result of the proposed reception antenna,and compares with focusing efficiency and F number of traditional Fresnel lens.%为了减小可见光通信接收系统的尺寸、提高聚光效率,依据传统的可见光接收天线——单面为锯齿的菲涅尔透镜,设计了一种新型的接收天线——双面均为锯齿的新型透镜.给出了设计方法和模拟结果,并将其与传统菲涅尔透镜的聚光率、F数等进行对比分析.
