一种高效均匀复合型菲涅尔透镜设计
Design of a high efficiency and homogenized compound Fresnel lens
摘要
Abstract
In view of the problem that the Fresnel lens antenna can not take into account the high concentration efficiency and uniformity in visible light communication system.A compound Fresnel lens is designed in this paper.Based on the partitioning method,the lens is divided into inner and outer ring regions,and the efficiency of Fresnel lens is improved.The method of distributed focusing is used to optimize the lens structure and improve the energy uniformity of the concentrator spot.The simulation results show that the compound Fresnel lens is achieved a uniform distribution of energy under a high concentration efficiency.The designed Fresnel lens is suitable for the application with small angle,high gain and short focal length in visible light communication system.关键词
