IR Acousto-Optic Devices using Acoustic Reflection

The paper investigates the peculiarities of bulk acoustic waves reflection in crystals of mercury halides in the case of an arbitrary incidence of an elastic wave on the free boundary between the crystal and vacuum. Unusual effects and phenomena, previously poorly studied by acoustics and fundamentally not observed in isotropic materials, are considered. Using results of the work, new versions of acousto-optic devices operating in the infrared range can be constructed.
