CMAM - Madrid

Informal seminars at the Accelerator

Description

The photoacoustic effect was discovered by Alexander Graham Bell in the late 19th century and was reported first in 1880.

The photoacoustic technique is a nondestructive spectroscopic technique that involves in the generation of acoustic waves from the absorption of the modulated or pulsed light on test material. This effect has been used since the middle of last century, however it was not until the '70s that was used as excitation source for the lasers that returned his application.

This technique has been used in characterizing a wide variety of materials, regardless of its nature. It has particularly proved a powerful tool to study phase transitions in condensed matter (solids, liquids, gels, suspensions, powders, etc.).. Some fields of application are: in medicine (photoacoustic tomography), cleaning and surface restoration, contaminant detection, etc.
