The peculiarities of image formation in photoacoustic microscope under piezoelectric detection

It has been shown that acoustic properties of the regions of the object located under the point of laser beam action and out of reach of the heat wave, play essential role in forming photoacoustic signal under piezoelectric registration. This fact can be used with the aim of visualization since the resulting photoacoustic topograms reflect the localization, shape and sizes of inhomogeneities sufficiently well
