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 lens can approach 180 degrees or even more. It can be utilized in a panoramic camera-projector as either a photographic lens or a projector lens. In this paper, the development of its structure is introduced, the theory of image formation is discussed, formulae of both the ideal image height and the stop spherical aberration are given. A practical example is finally given.
