Spatial-temporal light modulator based on total internal reflection violation in ferroelectric smectic C*

Possibilities of creating a spatial-temporal light modulator (STLM) with matrix electrodes using energy reflection coefficient modulator at the glass-LC boundary have been studied. Ferroelectric smectic C* which as the optical structural angle between the director and the normal to the smectic layer near 45 degrees is proposed as an LC-medium. The results of investigation make it possible to construct an LC-valve characterized by high transmission (approximately equals 90%) of nonpolarized light in a wide spectrum range in the open state.
