Abstract. The construction of acousto-optical display based on the hysteretic in cholesteric
liquid crystals (CLCs) is proposed for nondestructive holographic test systems. The
influence oblique reactive sputtering deposited thin films of In2O3, AlxOy, SiOx, upon
alignment properties of CLC, which are used as ultrasonic holographic recording media, is
investigated. The technical characteristics and properties of developed acousto-optical
display (AOD) are represented. The high sensitivity and planar texture reproducibility CLC
are shown to be implicit advantages of AOD developed.
Keywords: cholesteric liquid crystal, acousto-optical display, ultrasonic hologram
