The effectiveness of matrix-type spatial-temporal LC modulators used in information-array formation circuits depends not only on the electrooptic parameters of the modulating layer but also on the modulator design. New possibilities for using multichannel modulation of radiation in optical circuits intended for formation and retrieval of information arrays are opened up by the development of matrix liquid crystal displays (LCD) based on fiber-optic components. The work is concerned with the results of development and investigation of liquid-crystal matrix modulators on fibre-optic faceplates. The light transmission of the substrates employed was 0.75-0.80 in the visible spectral range, and the resolution was not worse than 60mm(-1). The modulator samples utilized the twist-effect and the effect of dynamic light scattering in nematic liquid crystals, the LC layer width was 10 mu m. The modulation characteristics were investigated on samples featuring different sizes and shapes of electrodes. It is demonstrated that the contrast provided by the spatial-temporal modulators on fibre-optic faceplate is enhanced owing to a reduced noise level in the output faceplate plane.
