Abstract
We use a spatio-temporal Fourier-transform approach and a perturbation technique to analyze acousto-optic interaction between an input optical beam of arbitrary profile and pulsed ultrasound. We write the sound field as a superposition of a time- harmonic constant-amplitude wave and a modulated pulse. While the scattering of the input light beam by the former component can be effectively handled using a spatial Fourier-transform technique, the additional contribution can be analyzed using a spatio- temporal Fourier-transform approach. Numerical results, calculated using the equivalent spatial and spatio-temporal transfer functions, are shown for the case of Bragg diffraction.
