This paper presents the simulation of an autofocus lens design with large depth of field for a cell phone camera. The object distance of the lens is from infinity to 9.754 mm. When the object distance is from infinity to 550 mm, the value of the modulation transfer function (MTF) is greater than 0.6 for the spatial frequency of 114 lp/mm, the optical distortion is less than 1.5%, and the relative illumination is greater than 67%. When the object distance is from 325 to 9.754 mm, the MTF values is greater than 0.4 for close-up shooting. The optical distortion is less than 1.454%, and the relative illumination is greater than 68.8%.
本文介绍了一款用于手机摄像头的大景深自动对焦镜头设计的模拟。该镜头的物距范围从无穷远到9.754毫米。当物距从无穷远到550毫米时,对于114线对/毫米的空间频率,调制传递函数(MTF)值大于0.6,光学畸变小于1.5%,相对照度大于67%。当物距从325到9.754毫米时,用于特写拍摄的MTF值大于0.4。光学畸变小于1.454%,相对照度大于68.8%。
