Abstract
Reflection X-ray topographs from acousto-optic devices were measured u nder surface acoustic wave excitation. Enhanced sensitivity to small u ltrasound amplitudes was achieved when the ultrasound wavelength was s horter than the X-ray extinction length. Under this condition an X-ray diffraction image of a high-frequency traveling surface acoustic wave was obtained despite the strains in the device caused by microelectro nic processing.
