Brillouin scattering (also known as Brillouin light scattering or BLS), named after Léon Brillouin, refers to the interaction of light with the material waves in a medium (e.g. electrostriction and magnetostriction). It is mediated by the refractive index dependence on the material properties of the medium; as described in optics, the index of refraction of a transparent material changes under deformation (compression-distension or shear-skewing).

"WebLight traveling through a quartz crystal can be diverted from its path by an acoustic wave. Light can be scattered off the areas of altered density caused by the acoustic wave in a process called Brillouin scattering. The analogy is made to Bragg scattering in that the sound waves produce effective planes for scattering the incident waves. " - Brillouin light scattering polycarbonate
