Resumen o descripción

Acoustic waves were studied extensively in the 19th century; surface acoustic waves were first described by Lord Rayleigh in 1885 as they pertained to earthquakes [1]. The acousto-optical effect was first studied or predicted by Brillouin in 1922 [2]. Physically, this effect describes the interaction between light and sound waves. This interaction produces the diffraction of light from the medium which was first perturbed by an acoustic wave. Later, in 1932 Debye and Sears [3] and Lucas and Biquard [4] verified it experimentally when optical sources of sufficiently high coherence become available. Surprisingly, a large number of diffracted orders were observed, symmetrically spaced about the undiffracted beam. Brillouin proposed that this effect was due to rescattering of light from the acoustic beam, it was quantified until a theoretical treatment using Feynman diagrams was presented in 1980 by Korpel and Poon [5]. This established a rigorous physical description of the multiple scattering of plane waves; a similar concept had been employed in a mathematical formalism first presented in 1960 [6].

The presence of multiple diffracted orders was first explained in a classic series of papers by Raman and Nath in 1935-1936 [7], who modeled the sound column as a phase grating acting in transmission to give rise to many diffracted orders by interference. They also considered the problem of oblique and arbitrary angle of incidence of light on the acoustic beam. Debye and Sears [3], who also derived a criteria for single- and multiple-order diffraction phenomena (Debye-Sears ratio).
