鱼眼显微镜光学

Fish-Eye Optics in Microscope

鱼眼镜头的视场角可以超过180度。它可以用作周视照相机镜头,也可以用作球幕电影的摄影和放映镜头。鱼眼显微镜光学是利用鱼眼镜头视场为180度,对有限远物体成象,与摄象机配套,可以把圆筒360度内壁上的物体,例如裂缝疵病,演示在电视屏幕上,起检测作用。文中附有一个实例,列出了镜头的结构参数,以及计算机输出的各种象差数据和相应的象差曲线图形。

The field angle of fisheye lens can be larger than 180°.It can be used as lens of panoramic camera,and it can be also used as photographing and projection lens of spherical screen film. The optics in fisheye microscope applies 180° field of fisheye lens to imaging of finite object in far field.In combination with camera,it can display the objects 360°inside the wall of circular tube,such as cracks and defects, on the television screen. An example in the paper cites the design values, various aberrtation data given by the computer and the corresponding aberration curves.
