Abstract

The study of structures in different materials is increasingly important. In many cases, these materials have different layers that compose them, and it is not easy to observe or detect some internal structures or damages without destroying the samples. Photothermal (PT) techniques, such as photoacoustic spectroscopy, photoacoustic (PAM) and photopyroelectric microscopies, are valuable nondestructive techniques. PT microscopies allow to make scans of samples in order to obtain their thermal images. In this study, thermal images of two different samples were obtained, by using PAM at different excitation wavelengths.
