Study of SAW propagation characteristics by frequency-translated holography

Abstract

Under the condition of continuous acoustic generation the patterns of forward, backward, and standing SAW’s propagating on a y-cut z-propagating LiNbO3 crystal were observed clearly by the frequency-translated holographic technique. The parameters of surface-wave propagation velocity, reflectivity, and transmissivity for an interdigital transducer could be obtained by this technique.
