Abstract

In transmission thermoacoustic scanning microscopy, the thermally induced bulk waves are detected on the opposite surface of the sample by a piezoelectric transducer or a laser probe. The use of a compact heterodyne interferometric laser probe enables high resolution and wide frequency range imaging. Such a microscope is described in this paper. Results obtained for inhomogeneous or layered samples are presented and discussed, showing potential applications.
