Abstract
A device () for speckle reduction, comprising an optical cell () and a controller (). The optical cell () comprises a first and second cell wall () spaced apart by a gap, and a liquid crystal composition () in the gap. The controller () is configured to cause fluid turbulence in the liquid crystal composition. The fluid turbulence in the liquid crystal composition () results in time varying spatially random scattering of light () transmitted through the liquid crystal composition (). The liquid crystal composition () has a chiral nematic phase.
