| 摘 要： | 鱼眼镜头是一种焦距极短但视角很大的镜头.紧凑型鱼眼镜头光学系统的工作波段在可见光范围内,全视场为172°,能很好地解决广角镜头的轴外像差和边缘像面照度问题.设计的鱼眼镜头光学系统具有结构简单、体积小、成像质量好的特点.系统总长80.9 mm,后工作距离为18.8 mm.所选像元尺寸为12μm×12μm,像素数为1 280×1 024时,CCD对应的空间分辨力为27.2 lp/mm,边缘视场的MTF值最小,优于0.60.设计结果较理想.

| Abstract: | Fisheye lens is one kind of special lens which has a very short focal length and a very wide field of view.A compact fisheye lens optical system is presented,whose operating wavelength range is in visible bands,and field of view is up to 172°.The fisheye lens system has the advantages of simplicity,compactness and good imaging quality.The total length is 80.9 mm and back working distance is 18.8 mm.The size of the pixel is 12 μm×12 μm and the number of pixels is set to 1 280×1 024.Its modulated transfer function value is higher than 0.60 when spatial resolution at the 27.2 lines/mm.The simulation result shows that the design is good. |
