摘要
鱼眼镜头的视场高达180°或超过180°,可以作为全景电影的摄影和放映镜头,本文介绍了它的结构型式的发展,讨论了它的成象理论,给出了适合它的理想象高公式和光栏球差公式,最后提供了一个实例。
The field angle of fish eye lenses can be made to reach or even surpass 180 degrees.It can be utilized in a panoramic cinema as either a photographic or a projection lens . its structrual development is introduced, the theory of image formation discussed, the formulae of both the ideal image height and the stop spherical aberration are given. Finally a practical example is shown.
