Enhancement in electro-optic properties of dynamic scattering systems through addition of dichroic dyes

Enhancement in electro-optic properties of dynamic scattering systems through addition of dichroic dyes

Electro-optic properties of dynamic scattering in homeotropically aligned pure and dichroic dye doped nematic liquid crystal samples are examined. The optical properties of the two systems are quantified using transmission properties of scattered and unscattered as a function of amplitude and freque...
