Abstract:
A system for detecting and controlling localized image intensity, for use in an intensified optical imaging system, comprising:micromirror array means further comprising an array of individually-controllable micromirrors, each of said micromirrors corresponding to and reflecting one of a plurality of localized regions of an input image reflected off of said micromirror array means as a reflected image, and each of said localized input image regions corresponding to at least one pixel of said input image;monitoring detector means for detecting a light intensity of each of said localized regions of said reflected image and identifying any of said localized regions that are saturated to intensity above a predetermined threshold; andcontrol module means for maintaining each micromirror for which the corresponding localized region is not so-identified to be above said threshold in a first energized position in which said corresponding localized region is reflected into imaging means through which said reflected image is to be imaged, and moving each micromirror for which the corresponding localized region is so-identified to be above said threshold into a second energized position in which said corresponding localized region is reflected away from said imaging means.
