Abstract
An optical system for recording or projecting a panoramic image which includes a flat transparent member, a mirror, a stem and a spherical body. The mirror is spaced from the transparent member in an axial direction, the mirror member having a reflecting surface facing the transparent member. The stem extends between and connects the transparent member and the mirror together. The spherical body has a reflecting surface spaced from the mirror in the axial direction. The reflecting surface of the spherical body is oriented with respect to the reflecting surface of the mirror such that light rays are reflected therebetween, the reflecting surface of the mirror being oriented with respect to the transparent member such that the light rays are also reflected therebetween. The optical system can be used for recording or projecting a panoramic image. The camera lens has a curvature closely matching the curvature of the reflecting surface of the spherical body. Film recorded by the camera can be used in a projector to project a distortion free 360.degree. panoramic image on a cylindrical screen.
