Photoacoustic Spectroscopy and Its Applications in Biology, Radiotherapy, and Imaging - A Brief Overview

The photoacoustic spectroscopy for non-destructive measurements has been developed in many attractive research areas. In this spectroscopy, high energy laser beam used for irradiating the material will be detected. Light beam will produce a thermal expansion (increasing in heat temperature) within the material, which is then generating an acoustic wave. This review paper presents the photoacoustic spectroscopy for biology, radiotherapy, and imaging applications.
