Abstract Gas-Coupled Laser Acoustic Detection (GCLAD) is an ultrasonic. non-contact detection technique that has been recently proven to be applicable to the inspection of mechanical components. GCLAD response raises as the intersection length between the probe laser beam and the acoustic wavefront propagating in the air increases; such feature differentiates the GCLAD device from oth... https://www.getpureroutine.com/special-pick-aus-309-darwin-to-penguin-shoal-fashion-great-offer/
