82‐4: Invited Paper: Speckle Reduction in Laser Projectors by Angular, Wavelength, and Polarization Diversities

Abstract

Speckle reduction by angular, wavelength, and polarization diversities are widely used to suppress speckle, but they are not fully understood yet. This paper summarizes these speckle reduction methods and shows novel experimental results and theoretical analysis, including the dependency of angular and wavelength diversities.
