Optical characterization by temporal deconvolution of one-dimensional laser-ultrasonics signals – Part 2 : experiment

Abstract : In an other contribution (also presented at the 9th ICPPP Conference), we expose the theory of a data processing technique that extracts the laser pulse duration-related convolution from 1D laser-ultrasonics signals and then allows the quantitative evaluation of both the optical absorption coefficient and the longitudinal acoustic velocity from the convolution-free signals. This paper is the continuation of that contribution, and consists in the experimental validation of the data processing technique.
