Optical generation and detection of elastic waves in solids

Abstract : In this paper we review optical methods suitable to generate and to detect elastic waves in solids without any mechanical contact. The mechanisms underlying elastic wave generation by the impact of a pulsed laser beam are outlined. The principles of optical techniques able to detect surface displacements of amplitude less than one angström are described. Examples of applications in domains such as nondestructive testing and acoustic field imaging are given.
