Abstract:
High resolution printing systems that utilize high power laser diode bars and digital mirror devices (DMD) require side-by-side stacking of illumination modules to stitching of the image from each module to form a longer total image width. An inline illumination optical system having a refractive prism and Total Internal Reflection (TIR) prism pair with an air gap along with a light guide transporting light beams at a compound angle to the prism pair eliminates the need for any axial rotation of the laser and light guide, and enables side-by-side module stacking. The illumination optical system includes an illumination module having a light source, the light guide, a DMD array and a Refractive TIR (RTIR) prism. The system also includes a DMD housing containing the DMD array and having a width within which the illumination module is confined to allow side-by-side stacking.

Claim (Index 18):
A method of illuminating a Digital Micromirror Device (DMD) array having a plane, comprising:\n redirecting a light beam in a first illumination module to the DMD array along a compound incident angle with a Refractive Total Internal Reflection (RTIR) prism, the first illumination module including the DMD array and the RTIR prism, with the DMD array in a DMD housing, the DMD housing having a width, the first illumination module being confined within the width of the DMD housing, the RTIR prism including a 45-45-90 degree prism and a compound angle prism, the compound angle prism having a 45 degree bottom face above a top face of the 45-45-90 degree prism with an airspace gap therebetween, the 45-45-90 degree prism having a bottom face mounted parallel to the plane of the DMD array; modulating the light beam with the DMD array to generate an image as reflected image output beams, the DMD array being an array of micromirrors with a row direction and a column direction orthogonal to the row direction, both the row direction and the column direction being within the plane of the DMD array; redirecting the reflected image output beams to the projection optics that images the DMD array onto the imaging member through the 45-45-90 degree prism; stitching the image output beams to image output beams from a second illumination module stacked against the first illumination module in a side-by-side configuration with parallel DMD row directions, the stitched image out beams forming an image line parallel to the row direction of the DMD arrays.
