Microcantilever Actuation by Laser Induced Photoacoustic Waves
We present here a combined theoretical and experimental investigation on effective excitation of microcantilever by using photoacoustic waves. The photoacoustic waves arose from a vibrating Al foil induced by an intensity-modulated laser. We demonstrate that, superior to photothermal excitation, this new configuration avoids direct heating of the microcantilever, thus minimizing undesired therm...
متن کاملDesign and Application of a Photoacoustic Sensor for Monitoring the Laser Generated Stress Waves in Optical Fiber
Measurement of stress transients generated by a 400ns pulsed HF laser in an infrared fluoride glass fiber has been made using fast time – response piezoelectric film transducer. Acoustic signals up to 12 mV with frequencies ranging in megahertz generated by 21 mJ laser pulse when passed through the fiber axis in the linear region. It is shown that useful information such as onset of non - linea...
متن کاملAdhesive Bond Testing By Laser Induced Shock Waves
Adhesive bonding of metal sheets presents many practical advantages when compared to other joining methods, but its application for critical components is limited by the absence of reliable nondestructive methods that can assure the bond strength of the joint. In this paper, a method based on shock waves produced by pulsed lasers is applied to the evaluation of adhesive bond strength of two alu...
متن کاملLaser Photoacoustic Spectroscopy
Fig. 7 — Principle of the photoacoustic effect. Photoacoustic spectroscopy (PAS), also known as optoacoustic spectro scopy, was pioneered by Alexander Graham Bell more than a century ago. The advent of the laser strongly stimu lated research and applications of this technique and the interest is such that international topical meetings on photo acoustic and photothermal phenomena are now hel...
متن کاملRestoration of laser-induced process kinetics from photoacoustic measurements
Reconstruction of the kinetics of relaxation processes induced in a medium by laser radiation is considered. Implementation of a-regularization algorithm of the ill-posed problem solution in optoacoustic (OA) diagnostics of liquids is discussed. The relationship between parameters of the diagnostic experimental set-up and the frequency band where relaxation spectra can be restored is establishe...
