Abstract

The scattering electro-optic cells of this proposal make use of media whose refractive indices can be controlled such as, for example, liquid crystals. Liquid crystals are birefringent, and depending upon the orientation of the liquid crystal molecules, incident light sees different refractive indices. If transparent isotropic crystallites, spheres, flakes, fibers or the like are embedded in the liquid crystal and the refractive index of the embedded materials matches the index n-of the liquid crystal, no scattering will occur if the Iftolecular orientation of the liquid crystal is such that light propagates with the index n0 in the liquid crystal.
