Lopez Física, Astronomía y Matemáticas non photoacoustic destructive testing Laser based ultrasound We studied experimentally the ultrasonic propagating modes produced by a laser pulse of 532 nm while impinging on an aluminum plate.The beam, shaped as a line, induced various Lamb modes whose relative power varied with the laser line length. Identification of their modewas performed by detecting the ultrasonic modes with piezoelectric detectors along a propagation direction orthogonal to the line, and usingtwo dimensional fast Fourier transform. Good agreement is observed between theoretical and experimental dispersion curves for the firstfundamental symmetric and anti-symmetric modes.
