An apparatus for producing a pixel-modulated line light source from a point light source in which a fiber optic bundle formed of individual fibers arranged in a cylindrical array forming a tip at one end and having the individual fibers spread to a substantially flat line of fibers at the other end optically coupled with an optical shutter means which is constructed of an array of aperture cells disposd in a straight line region aligned with the flat line of fibers. The transmissivity of the aperture cells is individually controllable by electrical signals.
