Speckle contrast reduction of laser light using a chiral nematic liquid crystal diffuser
High coherence in laser light causes spatially distributed interference called speckle. In applications such as holographic projection, this undesirable side effect degrades image clarity. The current methods of speckle reduction, such as a rotating ground-glass diffuser, require additional bulky mo...
