Abstract

Laser light deflection has been used to study microwave acoustic surface waves. In particular, the insertion loss versus frequency characteristics of interdigital transducers have been measured optically. Beam steering, caused by misalignment of transducers with pure mode axes, has also been measured and found to be a significant effect.
