Abstract
A two level image writer () forms an image from digital data onto a photosensitive medium. A first level illumination system has a first source () for emitting a first polarized light beam having a first color; a second source () for emitting a second polarized light beam having a second color; and a third source () for emitting a third polarized light beam having a third color. A fold mirrors directs each beam to a second level. Three polarizing beamsplitters () on the second level receive the polarized beams from the fold mirrors and isolate polarization states of each of the first, second, and third polarized light beam. Three spatial light modulators () on the second level modulate the first, second, and third polarized light beam from the polarizing beamsplitter prisms to form an array of image pixels according to said digital data. A diechroic combiner () combines the three modulated light beams.
