ABSTRACT:
A device including at least one image detection array and image formation optics that provide a field of view corresponding to the image detection array. At least one illumination module (which includes at least one source of coherent illumination) produces planar light illumination that substantially overlaps the field of view corresponding to the image detection array. Illumination control circuitry modulates the power level of illumination produced by the source of coherent illumination during each photo-integration time period of the image detection array to thereby reduce speckle noise in images captured by the image detection array. The illumination control circuitry preferably modulates the power level of illumination by controlling the number and/or duration of time periods corresponding to different power levels of illumination produced by the source of coherent illumination during each photo-integration time period of the image detection array.
