Abstract :
In this report we develop investigations which have been made to study the energy distribution of different type of surface acoustic waves in different devices using quartz and lithium niobate. The observations were performed with X-ray topographs obtained by the use of the synchrotron radiation. The time structure of the X-rays has permitted to obtain stroboscopic observations of the amplitude and phase distributions of the Rayleigh waves across the devices. Bragg and Laue patterns were obtained in order to analyse the components of the displacements. The most important results concern the interactions between the dislocations and the SAW
