摘要

设计了一款基于同心透镜的1300万像素超广角手机镜头,得到符合工业生产要求的手机镜头参数。该镜头由4片同心透镜组成,焦距为3.3 mm,F数为1.83,视场角为100°,总长5.18 mm。研究结果表明,在奈奎斯特频率为223 lp/mm处,0.7视场的调制传递函数(MTF)值均大于0.58,全视场的MTF值均大于0.50;在446 lp/mm处,0.7视场的MTF值均大于0.30,全视场的MTF值均大于0.17。各个视场的弥散斑半径均小于2.3 μm。全视场内相对照度值均大于0.65。

Abstract

One kind of 13 mega-pixel and super-wide-angle mobile phone camera is designed based on concentric lens and the parameters of the mobile phone camera that meet the industrial production requirements are obtained. This camera is composed of 4 concentric lenses with a focal length of 3.3 mm, a F-number of 1.83, a field of view (FOV) of 100°, and a total length of 5.18 mm. The research results show that, at the Nyquist frequency of 223 lp·mm-1, the modulation transfer function (MTF) value is larger than 0.58 in the 0.7 FOV and that in the whole FOV is larger than 0.50. At 446 lp·mm-1, the MTF value is larger than 0.30 in the 0.7 FOV and that in the whole FOV is larger than 0.17. The root-mean-square (RMS) radius of each FOV is less than 2.3 μm and the relative illumination value is larger than 0.65 in the full FOV.
