The generation of the optoacoustic signal (OAS) is caused by local thermal expansion in aqueous media under the influence of laser radiation. This mechanism is also called the generation of a thermoelastic OAS. A new physical explanation of the spherical profile of the OAS is presented. Using this profile, you can output signals generated by other geometric forms of the source and time profiles. The OAS is presented, which is generated by the spherical, cylindrical and linear form of the absorber. A physical explanation of this spherical form of the OSA is given. The theoretically OA effect from absorbers of different shapes can be practically applied in a flow cytometry method in vivo. The possibility of practical use of OA methods for diagnostics of body tissues is shown on the example of the developed functional scheme for diagnosing cells in the blood stream using the method of flow cytometry in vivo on the basis of OAS analysis.
