DETERMINATION OF CHARACTERISTICS OF OBJECT FLOW MOVED IN ELEMENT Russian patent published in 2017 - IPC A61B3/12 A61B5/00 A61B5/26 G01P3/36 G01P5/26 

FIELD: medicine.

SUBSTANCE: device comprises a light emitting unit configured to emit light in the element direction, a light detection unit, arranged to capture light scattered back to the element, an optical unit adapted to spatial separation of the light incidence portion of the element from the portion of the light detection element. The optical unit comprises a light path separation element which is adapted to divide the emitted light path and the backscattered path, and a determination unit configured to determine the flow characteristics of the object based on light indicating the emitted light and the detected backscattered light. The method is carried out by means of the device.

EFFECT: use of inventions allows to increase the sensitivity of measurement by improving the signal-to noise ratio.
