Abstract:
Two substantially one-dimensional scan line images are simultaneously generated by modulating a two-dimensional homogenous light field using a spatial light modulator (120) having light modulating elements (125) arranged in a plurality of rows and a plurality of columns. An upper group of modulating elements are configured using a first scan line image data group, and a lower group of modulating elements are configured using a second scan line image data group. The homogenous light source is then pulsed (toggled) to direct the two-dimensional homogenous light field onto the spatial light modulator. The resulting two-dimensional modulated light field is directed through an anamorphic optical system, which images and concentrates the modulated light on an imaging surface such that two parallel one-dimensional scan line images are simultaneously formed on the imaging surface.
