面向LED可见光通信系统的菲涅尔透镜设计与试验
Design and application of Fresnel lens for the visible light communication based on LED
摘要
Abstract
Aiming at the optical receiving efficiency of the visible light communication system is low,this paper designed a plane pitch Fresnel lens as a optical antenna for the visible light communication system.The influence of different parameters on the performance of the designed Fresnel lens is compared,simulations results show that the light-gathering efficiency of the designed Fresnel lens can up to 91%.The experimental results show that the signal to noise ratio of the system has been improved greatly by adding the Fresnel lens,the maximum value up to 21dB.The designed Fresnel lens is suitable for the small angle of field and high gain environment.关键词
