Diploma thesis abstract Igor S. Obolenskiy Scientific Advisor: Alexander V. Priezzhev Velocity measurement and visualization of microflows by optical techniques. In present work the measurement of velocities and visualization of microflows is performed in vitro in the artificial capillary with a stepped profile as well as in vivo in capillaries of a finder nail fold implementing compact computer capillaroscope. The microflow velocity profiles are reconstructed from the measurement results in artificial capillary in the region of stepped increase of capillary cross-section. The presence of the "dead" zone is shown behind the region of cross-section stepped increase. The polarization-sensitive modification of the capillaroscope is developed . This modification provides an increase in in vivo capillary image contrast due to detection of backscattered radiation with co- and cross-polarized filters relative to the probing radiation polarization.
