Image Projection Arrangement with Divergent Light Beams

Abstract

A lightweight, compact image projection module has a laser package having a
common exit port, and a plurality of lasers mounted in the package and operative
for emitting a plurality of laser beams of different wavelengths through the
common exit port. An optical assembly focuses the laser beams exiting the common
exit port, and includes a common focusing lens through which the laser beams
pass along respective paths that are in angular misalignment. An optical
corrector element in at least one of the paths corrects the misalignment to
produce aligned beams. A scanner sweeps the aligned beams in a pattern of scan
lines, each scan line having a number of pixels. A controller causes selected
pixels to be illuminated, and rendered visible, by the aligned beams to produce
the image. Image Projection Arrangement with Divergent Light Beams
