摘要
设计了一种用于图像拍摄的高分辨率大视场光学系统,其结构形式为复杂化的反摄远基本型.主要光学参量为:f′=6.59mm,2ω=62°,F数为2.2;在85lp/mm处,MTF达到0.8,在230lp/mm处MTF为0.46,基本达到衍射极限,光谱范围为0.486～0.656μm.设计评价结果表明,该系统的光学性能能够满足成像质量要求,达到了大视场、高分辨率的目的.
A optical system with large field of view and high resolution was designed. The structure of optical system is complicated inversed telephoto system. The capital optical parameters are f＇ = 6.59 mm, 2ω= 62°,F/number=F/2. 2. The imaging resolution was at 85 Ip/mm and 230 lp/mm, respectively, when MTF reached 0.8 and 0.46. The value was very close to diffraction limit. The spectrum range of designed optical system is 0. 486-0. 656μm. The evaluation of optical system shows that this system can suffice requirement of forming image.
