Paper Abstract

We propose a new opto-electronic method permitting the study of ordered structures in the optically transparent mediums and particularly the measurement of their phase speed. The validity of the process associating the optical Fourier transformation and interferometry is experimentally verified in applying it to the study of different modes propagating in an acoustic wave guide.
