The proposal of application of acousto-optical methods for nondestructive evaluation in the layered system described by O. Leroy and J. M. Claeys and the reconstructing of an ultrasonic field method used by Y. Nishida et al., have been reviewed. A suggestion is made to adapt the Nishida et al.'s, method of measuring the intensities in given light diffraction orders in pairs: I+1 + I-1, I+1 - I-1, I+2 + I-2, I+2 - I-2, ... to evaluate Raman-Nath parameters and phase shift between UW components for the layered system similar to that described by O. Leroy and Claeys.
