Аннотация:We consider one of the mechanisms providing light diffraction in layered structures disturbed by ultrasound. We show that diffraction can be observed when light is reflected from the surface in an area where there is no acoustic wave. Diffraction occurs due to the fact that the light receives a curved phase front when passing through an acoustic column
