ABSTRACT:
The laser illuminated image projection system includes a microlaser array coupled with a beam shaper to produce an exceptionally bright projection light beam. In one embodiment, the beam shaper includes a binary phase plate to modify the shape and intensity profile of the projection light beam. In another embodiment, the beam shaper includes a microlens array arrangement. In yet another embodiment, the beam shaper includes a diffuser arrangement. A light valve modifies the projection light beam to generate an output light beam indicative of an image. A projection lens arrangement focuses the output light beam onto a remote surface to reproduce the image thereon.
