Instrument for Studying the Oxygen Transport in Capillaries

A possibility has been studied of the process of oxygen transfer to the tissues through the capillaries. Oxymetry principle is applied at the microscopic level. A prototype of the device has been designed and manufactured based on a measuring microscope and a spatially high-definition videocamera. Proposed and designed is the illumination schematic. The instrument structure is described including its parts, as well as the idea of image processing, the latter being acquired in different sections of the spectrum. In the studies, the narrow-band illumination was used in the regions of spectral lines 527 nm, 585 nm, and 650 nm, that were selected by the interference filters with transmission bandwidths 10-12 nm.
