Капустина О.А., Лупанов В.Н. «Акустооптические свойства слоя нематического кристалла с гомогенной ориентацией» Журнал экспериментальной и теоретической физики, 71, № 6, с. 2324-2330 (1976)

We investigate the change in the structure and in the optical characteristics of a layer with homogeneous arrangement of the molecules of a mixture of the nematic crystals MBBA and EBBA acted upon by acoustic oscillations of frequency 3.2 MHz. It is shown that such layers can be used as an active element of a device for displaying acoustic information. Photographs are presented of acoustic images obtained with the aid of such a device, the operation of which is based on the effect of light scattering.
