Abstract
A new photothermal detection scheme based on a current-change in photothermally-enhanced electrochemical reaction is proposed and demonstrated. Nondestructive imaging of surface defects fabricated on a metal plate, immersed in an electrolyte, has been performed with a focused laser beam and detection apparatus of photoacoustic microscope (PAM). An imaging under the environment of electrolyte based on the principle of the detection was carried out with two- and tree terminal configurations, these results were compared with that obtained with conventional photoacoustic (PA) imaging.
