Abstract
A method and apparatus for monochromatic printing which records an image from digital image data onto a photosensitive medium ( ) is disclosed. The apparatus includes the following: A light source ( ) provides the monochromatic illumination. A uniformizer uniformizes a wavefront of light emitted from the light source ( ). A polarizer ( ) for filtering the uniformized light provides a polarized beam having a predetermined polarization state. A spatial light modulator ( ) has a plurality of individual elements capable of altering the polarization state of the polarized beam to provide an exposure beam for printing. A state of each of the elements is controlled according to the digital image data. An optics assembly ( ) is used for directing the polarized beam to the modulator and the exposure beam from the spatial light modulator ( ). A lens assembly ( ) is used for directing the exposure beam onto the photosensitive medium ( ).
