medicine. SUBSTANCE: the device has two sources of laser radiation, system for formation of light beam fed to the material under examination, seat for placement of a translucent flask with the material under investigation provided with a heater, system for formation of that part of the light beam scattered by the material under investigation, whose longitudinal axis is directed at an angle of 20 deg. to the axis of the light beam fed to the material under investigation, and a detector of the formed part of the light beam scattered by the material under examination receiving the light signal at observation angles varying within 0 to 20 deg. One source radiates light in the red spectral region, and the other - in the near-infra-red region, the sources are so installed that the light beams formed from their radiation would by directed at an angle relative to one another, and a semitransparent glass is installed in the point of their intersection, the source of laser radiation and the system for detection of the formed part of the light beam scattered by the material under examination corresponding to it are installed on different sides relative to the flask. EFFECT: enhanced accuracy and truth of examinations. 1 dwg
