Abstract

A novel method for achieving well-behaved far-field laser illumination of remote targets for imaging is described. An assembly based on a mixing rod modifies the laser output to give uniform illumination of a remote target and the laser footprint on target can be closely matched to the detector field of view. Polarization is maintained through the assembly, and power losses are slight. Laboratory test performance is presented for both a dye laser and an excimer laser system.
