A method of spectroscopic analysis of a material using a laser ultrasound system. The method includes measuring amplitude displacement of a target surface that has been excited with a generation laser. The amplitude displacements relate to the target's optical absorption properties. Amplitude displacements are generated over a range of laser wavelengths to obtain an optical absorption signature useful to identify the target material composition characteristics.
Procédé danalyse spectroscopique dun matériau à laide dun système à ultrasons laser. Le procédé comprend la mesure dun déplacement damplitude dune surface cible qui a été excitée avec un laser de génération. Les déplacements damplitude concernent les propriétés dabsorption optique de la cible. Des déplacements damplitude sont générés sur une plage de longueurs d'onde laser pour obtenir une signature dabsorption optique utile pour identifier les caractéristiques de composition de matériau cible.
