Description

Photoacoustics in solids provides a useful technique for both characterization of material properties and the detection of defects. In photoacoustics, a periodic thermal source is used to generate an elastic wave. Typically the thermal source is a laser or charged particle beam, however other sources are currently being investigated. A need for other sources is required for objects which have reflective surfaces or are too large to fit into a vacuum chamber, such as large metallic structures.
