Abstract

An apparatus for printing high resolution images on a photosensitive media (140) includes an array of LEDs (12) for forming a light beam uniformizing optics (45) and a condensor lens (70) which transforms the light beam to a telecentric beam. A polarizing beamsplitter (80) splits said telecentric beam into a first polarized beam and a second polarized beam and directs the first polarized beam to a first reflective LCD modulator (90) and directs the second polarized beam to a second reflective LCD modulator (95). The first reflective LCD modulator (90) rotates a first polarization state of the first polarized beam on a site by site basis to produce a first modulated polarized beam and reflects the first modulated polarized beam, in response to a first image data signal, through the polarizing beamsplitter (80). The second reflective LCD modulator (95) rotates the a second polarization state of the second polarized beam to produce a second modulated polarized beam and reflects the second modulated polarized beam, in response to a second image data signal, through the polarizing beamsplitter (80). A print lens(110) focuses the first and said second modulated polarized beams on the print media (140). In the preferred embodiment, the media is exposed in a color sequential manner with a two-dimensional color image. The media or the assembly may then be moved to a second position and a new image is printed.
