| 英文摘要 | 介绍了一款用于监控的短焦距超广角镜头的设计,光学系统采用反远距光学结构,根据设计要求,采用等距离投影成像方式。用zEMAX软件进行优化设计,合理地解决了边缘视场光照度和轴外视场像差的问题。对该结构特点进行分析评价并给出了各种像差曲线和调制传递函数(MTf)曲线。该镜头采用7组10片式结构,全视场角和相对孔径分别为175°和1/1.8,反远比为2.4。使用1/3InCH(1InCH=2.54CM)CCd成像传感器,全视场MTf值在100lP/MM处达到0.5,光学系统结构紧凑,像质优良。; The optical design of a short focus and ultra-wide field of view(FOV)lens used for monitoring is discussed.The optical system uses inverted telephoto optical structure.The equidistant projection imaging mode is adopted according to the design requirements.The Zemax software is adopted to optimize and design the system.The marginal FOV illumination and off axis aberration are solved.The structure features of the lens are discussed and the aberration curves and medulation transfer function(MTF)curves are showed.The lens has a structure of 7 groups and 10pieces.The marginal FOV and relative aperture of the final design is up to 175°and 1/1.8 respectively,and inverted telephoto ratio is 2.4.Using 1/3″CCD imaging device,full FOV MTF value reached 0.5 at 100lp/mm.Optical system has compact structure,excellent image quality.; 国家自然科学基金(11104234); 校级教改项目(JGZY201234) |
