在无线光通信领域 ,利用非成像光学设计的集中器能够聚集光辐射能量 ,而且相对于成像性集中器具有更紧凑的结构和更高的增益。利用光线追迹法对半球形集中器的性质进行了分析与研究。对好几种非成像集中器 :半球形集中器 ,复合抛物线形集中器 ,介质内部全反射集中器 ,多表面集中器 ,多相介质集中器 ,从设计原理、增益和视场进行比较 ,并分析其应用场合。
In the field of wireless optical communications, concentrators utilizing non-imaging optical designs are capable of concentrating optical radiation energy and have a more compact structure and higher gain relative to imaging concentrators. The properties of hemispherical concentrators are analyzed and studied by ray tracing method. For several non-imaging concentrators: a hemispherical concentrator, a compound parabolic concentrator, a total internal reflection concentrator in a medium, a multi-surface concentrator, a multiphase media concentrator, the design principle, gain and field of view are compared Analyze its application.
