1. A liquid crystal optical waveguide, which comprisesa transparent substrate,a transparent plate spaced from said substrate parallel therewith,a liquid crystal waveguide medium placed between said transparent substrate and said transparent plate in surface contact therewith and having an index of refraction greater than that of said substrate and said plate,means to apply an electric field to said liquid crystal to cause dynamic scattering,means to couple light into said liquid crystal waveguide medium so that the light is guided through the liquid crystal medium between said substrate and said transparent plate in a direction paralleling said substrate and said plate, andmeans to couple light out of said liquid crystal medium.
