Abstract
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 characteristics.
