We present a method for determining discrete points on the SAW mode at equidistant wavenumbers that requires only a single measurement, overcoming these speed limitations. A pulsed laser, shaped into an array of equidistant lines, generates elastic waves on the sample surface. A vibrometer detects the resulting surface displacement next to the line array.
