Abstract
We report the detection of surface acoustic waves on metals using a Michelson-type fiber optic interferometric sensor. Surface acoustic waves generated along an aluminum bar are detected by a miniature fiber optic probe placed between an acoustic transmitter and a piezo-electric receiver. Extensions towards measuring acoustic wave velocities are considered.
