可见光通信中菲涅耳透镜仿真设计与优化
Simulating and optimizing of Fresnel lens in visible light communications
摘要
Abstract
Visible light communication is a novel wireless optical communication technology based on white LED techniques. It has some advantages, such as the high emitting power, no electromagnetic interference and so on. Compared with traditional lens, Fresnel lens can be used in designing an optical reception antenna to reduce cost, thickness of lens and focal length. The designing, simulating and optimizing of Fresnel lens are addressed. The technique requirements and methods for design, simulation and parameters setting are analyzed. Some simulating results and performance analysis are also given. By using optimization, it can reach a good performance. Light collection rate at about 90% can be obtained, which ensures that the F number is less than 1 under the condition where the size of the detector is 1.5 mm×1.5 mm, which can support the antenna design.关键词
