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 13):
An illumination optical system, comprising:\n a plurality of illumination modules stacked against each other in a side-by-side configuration, each illumination module including:\n a Digital Micromirror Device (DMD) array having a plane, and \n a Refractive Total Internal Reflection (RTIR) prism configured to receive a light beam from a light source and redirect the light beam to the DMD array along a compound incident angle, 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 an bottom face mounted parallel to the plane of the DMD array, the DMD array configured to modulate the light beam and generate an image as reflected image output beams, the 45-45-90 degree prism configured to direct the image output beams onto the imaging member; and \n a DMD housing containing the DMD array, the DMD housing having a width, the illumination module being confined within the width of the DMD housing, wherein the plurality of illumination modules are stacked against each other in a side-by-side configuration with parallel DMD row directions for stitching of the image output beams of each illumination module into an image line parallel to the row direction of the DMD arrays.
