ABSTRACT The laser-holographic system is designed for investigating the dyna- zilic state of the human organism through the detection of the human skin vibrations, due to the state of the cardiovascular system and other sys— tems and organs, on a holographic interferogram with subsequent automa—tic working by an electronic computer. With the two—xz1se regime of a ruby laser and having synchronized the process of recording holograms of the thorax region in different phases of the cardiac cycle it is possibleto detect corresponding holographic interferograms of the human thorax. The distribution of interference bands over the surface of the thoraximage, corresponding to the field of the surface spots displacements,allows to receive the insight about the nature of cardiac noise and abo- ut the functional state of a &Litable valve or section of the cardiac muscle as well as information about the regional and local hemodynamics over the whole region of the thorax. 1.
