The analysis of interaction of a light with a biological tissue is held under requirements of existence a pulsewave of a blood. The connection between the performances of a tissue and parameters of a light, which one interaction with a tissue sets. The procedure of definition of scattering factors of a biotissue іn vіvo designed. The experiments on definition of the optical performances of an alive biological tissue are held. The scattering coefficients in range 565 - 660 and 880 - 940 nm are determined. The examinations of change of scattering coefficients in infrared light are held in the field of local inhomogeneity of a biological tissue. The method of definition of relative volume of a blood designed, which one is founded on measuring of the relation of modulation indexes of scattered light by a pulsewave of a blood on two lengths of waves at simultaneous measuring of oxygen arterial blood saturation. Explored changes microcirculation blood flow under influencing of a laser radiation. The temperature effect on quantity of a laser-induced photodissociation of an oxyhemoglobin is learnt. The connection between primary and secondary amplitude-time characteristics photopletysmography with parameters of a homodynamic and performances of a state of cardiovascular system of the person is explored.
