Abstract: FIELD: medicine. 
     SUBSTANCE: invention relates to medicine, namely, to ophthalmology, and can be used for non-contact colour Doppler mapping of the blood flow in the retinal and optic nerve vessels. Digital MV scans of optical coherence tomography (OCT) in the spectral area are obtained. Separate MV scans therein constitute combinations of V scans from consecutive scanning of the same examined tissue sample of the human eye. Spectral factorisation of the MV scans into V scans for a combination of spectral bands in the spectrum of the OCT interference signal, formation of a flow image accounting for the quantitative decorrelation values for the combination of spectral bands, image segmentation are executed. The density of the vascular network is calculated as a percentage of the segmented internal lumen of the flow in the total volume of the segmented image, and the volumetric blood flow rate is calculated based on the density of the vascular network and the flow index. Each V scan from all obtained digital MV scans is therein divided, as a result of multi-stage processing, into a thematic map of speckle structures and a thematic map of anatomical structures. The thematic maps of speckle structures are therein used to estimate the volumetric blood flow rate, followed by forming a colour Doppler thematic map. The thematic map of anatomical structures is converted into a background image. 
     EFFECT: method provides an increase in the efficiency of identification of biological fluid flows and determination of the quantitative characteristics thereof due to the separate processing of interference signal segments corresponding to the speckle structures and actual anatomical structures of the examined object.
