In work methods of generation of an optoacoustic signal for studying biological tissues are considered, the advantages of the method are shown. Ultrasound studies of biotissues are based on the detection of mechanical properties in biological tissues, ultrasonic methods do not allow to establish the level of oxygen saturation or hemoglobin concentration. Optoacoustic methods can allow to determine the properties of tissues and give images with high contrast at high ultrasound resolution in relatively large volumes of biological tissues.
