Abstract

A unique projector has been developed that projects a dynamic scene from successive images on film in both the visible and infra-red portions of the spectrum. The theory, construction, and performance of the projector, called the SCANAGON, is presented.1 It is truly flickerless, having a negligible illumination variation from scene to scene. Each successive image is "wipe-dissolved" into the previous image in a smooth transition by means of an unusual mirrored scanner. Used with the BLY cell, it projects a dynamic scene from motion picture type film into the visible wavelength side at up to 4500 foot-Lamberts, which will saturate the cell. A black-body source may also be used in conjunction with a film which modulates infrared radiation. The images can be programmed to flow at a rate from zero to several hundred frames per second, forward or reverse.
