| 摘 要： | 充分考虑了鱼眼镜头的特点,设计了一款应用于汽车后视系统的短焦距超广角镜头。系统焦距3.2mm,F数为2.0,全视场角179°,系统总长17.5mm。采用6片式结构,所有镜片均为球面未采用非球面,大大降低了成本,并对各像差曲线进行了分析,全视场MTF值在100lp/mm达到0.5以上,系统结构简单紧凑,像质优良。

| Abstract: | Considering the characteristic of fish-eye lens, the optical design of a short focus and ultra-wide field of view lens used for backing system is discussed. The focal length of the fisheye optical system is 3.2mm,the F number is 2.0,the field of view is 179°,and the system's length is 17.5mm. This design have a structure of 6 pieces that all are spherical surface. The aberration curves and MTF curves are shown and full field view MTF value reached 0.5 at 100lp/mm. This system has a compact structure and excellent image quality. |
