Abstract

Nematic layers with a fine-domain random planar structure obtained using nonrubbed polymer alignment films exhibit a mixed, partly regular and partly diffuse transmission with complementary high-contrast channeled spectra of the regular and diffuse transmittances. We show experimentally that the power of the light scattered by such a layer can be controlled by an applied electric field. We demonstrate that under certain conditions, when a layer with random planar alignment is illuminated by a quasimonochromatic light beam, the power of the scattered component of the light transmitted by the layer has a nonmonotonic dependence on the voltage applied to the layer and that there are electrically-induced states in which the layer scatters all the transmitted light and states in which the layer scatters only a very small portion of the transmitted light. These features allow using electrically-driven cells with such layers as polarization-independent tunable diffusers.
