The paper presents results on the theoretical and experimental investigations of an acousto-optic modulator based on single crystal lithium niobate. The modulator uses a regime of operation with a standing longitudinal acoustic wave generated in the

A theoretical investigation of mixed isotropic-anisotropic Bragg diffraction of light by ultrasound is presented. This case of acousto-optic interaction appears as isotropic and anisotropic scattering taking place simultaneously, and is typical only

The Raman-Nath, intermediate and Bragg regimes of acousto-optic interaction in an acoustically anisotropic medium are theoretically examined in the paper. The general model of the interaction is extended over the case of an elastically anisotropic me

The feasibility of air-coupled ultrasound transducers to detect laser-induced ultrasound from artificial blood vessels embedded in an optically scattering phantom is demonstrated. These air-coupled transducers allow new applications in biomedical pho

A quantitative method of evaluation of phase mismatches and calculation of intensities of diffracted light is described in the paper. The analysis is carried out for the case of the acousto-optic interaction taking place in an acoustically anisotropi

The feasibility of on-line monitoring variations in the weight of a coating applied on a textile carrier by means of air-coupled ultrasound is demonstrated experimentally. To that purpose, coating layers of weight varying between 25 and 95 g/m/sup 2/

An air-coupled NDE-system has been used for the inspection and imaging of discontinuities and inhomogenities in different kinds of materials, such as coating variations on tissue, spot welds on steel, and air inclusions in metal plates and welds. The

Optically isotropic media which are susceptible to acoustically induced birefringence can be used as acousto- optic polarization converters. A comparative study between fused silica and dense flint shows that at normal light incidence 52% of the ligh

If light is diffracted by ultrasound in an isotropic medium with acoustically induced birefringence, the state of polarization is modified in each order of diffraction with respect to the initial state of polarization of the incident light wave. In t
