Abstract
An acousto-optic cell can be characterized in terms of the spatial impulse response or a transfer function that relates the angular plane-wave spectrum of the output light field to that of the input light field. A general methodology for calculating the acousto-optic impulse response and transfer function is developed. This methodology is then specifically applied to the case of acousto-optic cells with and without Hamming apodization of the sound field. Results are obtained and compared with analytical expressions for the conventional Bragg cell for a typical value of the Klein–Cook Q parameter and sound intensity. Finally, implications of the results relating to beam shaping in the scattered light field are discussed.
