The potential to create a remote, contactless, diagnostic method for biological tissues or materials with properties similar to those of biological tissues, so-called phantoms, is studied. The method is based on measurement of local oscillations of the surface of material under study under the action of acoustic and ultrasonic waves. The application of a laser-scanning vibrometer provides a means for visualization oscillations of a biological tissue phantom with model defects in the form of air bubbles, regions with higher density, and laminations, and allows determination of the positions of these defects.
