Abstract:
1. A film recorder comprising: a plurality of light sources each generating a light beam; a spatial light modulator assembly including at least one linear diffractive spatial light modulator (LDSLM) to receive and modulate light beams from the plurality of light sources; a film transport for transporting a photographic film on an imaging plane; imaging optics disposed in a light path between the spatial light modulator assembly and the imaging plane to image modulated light beams from the spatial light modulator assembly onto a linear portion of the photographic film; and a controller, wherein light beams from the plurality of light sources are offset from one another on the imaging plane, and wherein the controller controls operation of the plurality of light sources, the spatial light modulator assembly, and the film transport to sequentially expose the linear portion of the photographic film to modulated light beams from each of the plurality of light sources.
