ABSTRACT OF THE DISCLOSURE Deflection and modulation of monochromatic light is achiev d by providing an about 1 micron to about 6 micron thick layer of homogeneously aligned nematic liquid crystalline material having negative dielectric anisotropy between two trans- parent electrodes; applying a voltage between the two electrodes at a voltage level above the threshold voltage level for parallel variable diffraction mode for said nematic liquid crystalline material, directing a ribbon or beam of monochromatic light into the layer of nematic liquid crystalline material and coplanar therewith; and increasing and decreasing the applied voltage so that light diffracted by the parallel variable grating mode nematic is deflected at an angle which either exceeds or is less than a critical angle .theta.c. When the deflection of diffracted light is in- creased in excess of critical angle .theta.c the incident monochromatic light is diffracted through the nematic layer and the electrodes; and, when the deflection angle of the diffracted light is decreased below critical angle .theta.c the incident monochromatic light is totally reflected within the nematic layer provided the voltage level is above the parallel variable grating mode level. At voltages below the parallel variable grating mode threshold voltage level, the incident monochromatic light passes through the layer of nematic liquid crystalline material without reflection. Imaging devices utilizing the above deflection and modulation are disclosed.
