Abstract
Photoacoustic imaging is a promising method for visualizing biological tissues with optical absorbers. This article provides an overview of the rapidly developing field of photoacoustic imaging. Photoacoustics, the physical basis of photoacoustic imaging, is analyzed briefly. The merits of photoacoustic technology, compared with optical imaging and ultrasonic imaging, are described. Various imaging techniques are also discussed, including scanning tomography, computed tomography and original detection of photoacoustic imaging. Finally, some biomedical applications of photoacoustic imaging are summarized.

Generation of shear waves by laser in soft media in the ablative and thermoelastic regimes

TL;DR: In this paper, the authors describe the generation of elastic shear waves in a soft medium using a laser beam and show two different regimes depending on laser energy, namely, a thermoelastic regime caused by a local dilatation resulting from temperature increase and an ablative regime due to partial vaporization of the medium by the laser.
