Abstract
An optical‐spatial filtering technique for studying complex, high frequency, standing and traveling acoustic surface waves is described. The relative amplitude distribution is directly displayed, and the wavelength and velocity are accurately measured. The velocity for z propagation on a y‐cut LiNbO3 crystal is found to be 3472.5 ± 1.5 m‐sec−1.Keywords
