Using noise speckle pattern for the measurements of director reorientational relaxation time and diffusion length of aligned liquid crystals

This study proposes a simple alternative purely linear optical approach based on noise scattering and speckle analysis to extract aligned liquid crystal diffusion length and director relaxation time. This method relies only on noise induced director fluctuations and does not use any voltage or optic...
