Paper Abstract

Thermoacoustic imaging permits the detection of surface and subsurface inhomogeneities in solid samples. In the scanning transmission microscope the periodic heating of the sample is realized by a power modulated laser. The thermally induced elastic waves are detected, on the opposite face of the sample, by an heterodyne laser probe. The noncontact testing system is described and compared to the optical microscope. The images of defects in solid samples are presented.
