SYSTEME UNG VERFAHREN ZUR SPECKLE-REDUZIERUNG DURCH BANDBREITENERHÖHUNG |
摘要 |
<p>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 Deltalambda<SUB>i </SUB>centered at some arbitrary wavelength lambda<SUB>0i</SUB>. The elements of the array are allowed, by design, to have a slightly different central wavelength, thereby creating an ensemble bandwidth DeltaLambda which is much greater than the bandwidth Deltalambda<SUB>i </SUB>of any individual emitter in the array. The resulting increased bandwidth reduces speckle in a displayed image.</p> |
