紫外通信中大视场光学天线具有重要的作用和意义。在目前常用的复合抛物面聚光器(CPC)的基础上引入双反射面构成了一种新型光学天线。双反射面能够有效地滤除可见光和红外光。通过对双反射面进行理论推导和光线追迹,得到双反射面能够有效增加CPC视场的结论,最后应用TracePro软件对双反射面和CPC进行建模和仿真,对探测器接收面进行视场和照度分析,为进一步的优化提供了依据。

Wide field optical antenna is of great significance in ultraviolet communication. Based on present compound parabolic concentrator (CPC) commonly used, a kind of new optical antenna is proposed base on two-surface reflection. Visible and infrared light can be effectively eliminated by two-surface reflection, after the theoretical deduction and ray tracing of two-surface reflection, the conclusion that two-surface reflection can increase the field of CPC effectively is derived. Finally the TracePro software is applied to conduct the modeling and the simulation on two-surface reflection and CPC, the field of view and illumination analysis of detector position is also presented. The result provides the basis for further optimization.
