Abstract
An apparatus for printing high resolution images on a photosensitive media (,) includes an array of LEDs (,) for forming a light beam uniformizing optics (,) and a condensor lens (,) which transforms the light beam to a telecentric beam. A polarizing beamsplitter (,) 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 (,) and directs the second polarized beam to a second reflective LCD modulator (,). The first reflective LCD modulator (,) 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 (,). The second reflective LCD modulator (,) 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 (,). A print lens(,) focuses the first and said second modulated polarized beams on the print media (,). 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.
