摘  要:文章设计了一个环形孔径折叠型超薄相机的光学镜头。相机镜头的焦距为 20 mm,视场为 16°,等效入瞳直径为15 mm。设计的相机镜头具有较好的成像质量,其全视场调制传递函数(MTF)在奈奎斯特空间频率处达到 0.4 以上。整个相机仅采用了一个光学元件,光学结构占用的空间极小,总长为 8.15 mm,仅为同性能的传统镜头的三分之一。

Abstract:A circular aperture folded-type optical lens of ultrathin camera is designed in this paper. The focal length of camera lens is 20 mm,the field of view is 16°,and the equivalent entrance pupil diameter is 15 mm. Designed camera lens has good imaging quality,and it’s modulation transfer function(MTF) for the whole field of view is above 0.4 at Nyquist spatial frequency. The whole camera uses only one optical element,optical structure occupies a very small space,the total length of it is 8.15 mm. It is only the 1/3 of the traditional lens with same performance.

Keywords:optical design;ultrathin lens;circular aperture
