Abstract
A method and system whereby a narrow linewidth coherent laser source when transmitted as a plurality of output signals and subsequently detected at a distance appears to produce the uniform illumination characteristics of an incoherent source thereby suppressing laser speckle and environmentally induced scintillation effects. A master oscillator source is split into N signals, each of which is independently phase modulated by frequencies designed to minimize a derived apparent incoherence factor. The signals are then either directed to an object to be illuminated so that they overlap at the object or first recombined and directed to the object.
