A new optical feedback interferometer for measuring red blood cell velocity distributions in individual capillaries: a feasibility study in microchannels

摘要

The dynamics of blood flow in microvascular networks is of great importance in the exchange of nutrient and waste substances between blood and living tissues. In these vessels of diameter less than 100 jxm, the development of quantitative methods for measuring the velocity of red blood cells (RBCs) is still challenging. In this context, the dual-slit (DS) technique, a temporal correlation technique first introduced by Wayland and Johnson (1967), is commonly used.
