  • Patent number: 4113367
    Abstract: The present invention provides a multifaceted reflecting polygon scanner system that is suitable for incorporation into a projector, camera, or other optical scanning or image immobilizing apparatus. The rotating reflecting optical system of the present invention, is capable of being combined with a continuous film transport to produce an overlap frame dissolve of sequential frames for optical immobilization of a projected image. The present invention includes a primary roof reflecting polygon, a secondary reflecting polygon, and an image surface. By proper choice of the polygon parameters and their juxtaposition relative to the image surface, the present invention uniquely provides a significantly higher relative aperture with minimal kinetic aberrations such as dynamic keystone distortion and minimal static aberrations. In one embodiment, a pair of roof reflectors of a 60.degree. and 90.degree.
