Abstract

Acoustic modulation of light scattering from a linear centrosymmetric array is analyzed by considering far-field contributions due to optoelastic (OE) effect and acoustically induced translation of the array elements. The modulated light intensity is shown to vary sinusoidally at the acoustic frequency when the physical constants representative of the above effects are within ranges of their physical limits. The OE and translation components of the acousto-optic (AO) signal are shown to be in phase quadrature, each exhibiting a double-sided maxima when expressed as a function of the detector angle.
