Abstract: A Schlieren-type color television projector utilizes a fiber optic rear projection screen (FORPUS) at an initial focal point to translate the spatially separated, converging rays of component colors produced by the Schlieren-type color television projector into a plurality of spatially combined, diverging rays of combined colors which are then suitable for further processing by a conventional optical lens system which can either aperture or vignette the image without color fringing, separation, or a shift in the color balance normally experienced when aperturing or vignetting a Schlieren-type color television image.
