Abstract
An apparatus and method for producing multi-color, continuous tone images on a photographic element sensitive to radiation outside the visible region of the electromagnetic spectrum includes at least two laser diodes which may be simultaneously modulated, beam combiners to combine radiation emitted by the laser diodes into a single colinear beam and a rotating polygonal mirror for scanning the combined colinear beam across the surface of the photographic element.
