SYSTEM FOR UNIFORMLY ILLUMINATING TARGET TO REDUCE SPECKLING

摘要

An illumination system for uniform illumination of a target to facilitate imaging of the target by an imaging system. The apparatus which comprises a laser source for generating a plurality of independent or quasi-independent point sources of light; a fiber optic bundle which comprises a plurality of individual optical fibers for each receiving at least one of the plurality of point sources of light, from the laser source, and directing the plurality of point sources of light toward the target for illumination thereof; and an oscillating diffuser for receiving the plurality of point sources of light and oscillating at a frequency so as to redirect each one of the plurality of point sources of light over an area of the target to be illuminated to facilitate uniform illumination and imaging thereof.
