Abstract
A laser imaging system with reduced speckle is disclosed. The laser imaging system includes spatially superpositioned 1-D arrays or alternatively 2-D arrays of independent emitters of laser radiation, with each emitter having a spectral bandwidth Δλcentered at some arbitrary wavelength λ. The elements of the array are allowed, by design, to have a slightly different central wavelength, thereby creating an ensemble bandwidth ΔΛ which is much greater than the bandwidth Δλof any individual emitter in the array. The resulting increased bandwidth reduces speckle in a displayed image.
