Abstract

Spatial coherence in imaging has one notorious consequence: speckle. It corrupts images and limits laser use in applications ranging from modern microscopy to digital light projectors to photolithography. Most approaches for eliminating speckle involve time-averaging independent speckle patterns, which limits the imaging speed. We have taken a different approach-instead of averaging out the speckle that is already present, we prevent speckle formation by using an unconventional random laser.
