title: Electrophotographic imaging with cholesteric liquid crystals.
abstract: A new electrophotographic imaging process using mixed cholesteric liquid crystals and a xerographic plate is described. The liquid crystals have a bistable behavior and are switched by the imaging process. For a given angle of illumination and observation, the most strongly reflected wavelength differs by several thousand angstroms in the two states. A shift between these states can be produced by direct mechanical disturbance or by the indirect action of an electric field which causes a migration of material.
