摘　　要：通过光学设计软件ZEMAX设计了一款可适用于安防监控摄像头中的同轴照明方案。该方案由成像系统和照明系统组成。首先设计了一款可用于监控视频摄像用的大光圈成像物镜,具有焦距光圈数为F1.8的大光圈视频监控摄像镜头;然后设计了满足成像镜头可用的照明系统,该照明系统采用的是同轴光照明设计,使用普通的朗博体LED芯片作为光源,通过本设计提供的照明光路实现光源的准直匀光和整形,将光束投射到物镜系统中;再从成像物镜中投射到被照明表面。整个方案结构简洁,不需要单独开孔安装照明装置,照明效果的均匀性好,易实现加工要求,具备很好的商用前景。In this thesis,a type of co-axial lighting for security camera was set up in ZEMAX.The solution consists of an imaging system and an illumination system.First,a large-aperture imaging objective lens that can be used for surveillance video cameras is designed.It has a large-aperture video surveillance camera lens with a focal length of F1.8.It is a co-axial light illumination design,using ordinary Lamborghini LED chips as the light source,through the illumination light path provided by this design to achieve collimated uniform light and shaping,and project the light beam into the objective system;then the light beam is further projected from the imaging object mirror to the illuminated surface.The whole scheme has a simple structure,no need to install lighting devices with separate holes.The uniformity of the lighting effect is good,the processing requirements are easy to achieve,and it has a good commercial prospect.
