ABSTRACT:
A portable illuminator for use in an atmosphere of fog, haze or particulate matter includes a laser for generating a light beam, and a light-beam scanner for scanning the laser beam over a line or area to be illuminated. The scanning may be accomplished by mechanically moving the mirror or the laser, or a moving lens may be used. In another embodiment, a microelectronic scanning reflector is used.
