Abstract
Flows with complex geometries, converging flows in a symmetric die-entry and an asymmetric oblique die-entry are investigated by means of direction sensitive one specific velocity (OSV) imaging. Near infrared, 1.3 nm, low coherence source giving resolution of about 10 micron is used for two-dimensional velocity mapping of the flows. Structural optical coherence tomography (OCT) images of a Y-junction of human subcutaneous macro blood vessels, with diameter up to 1 mm, are acquired noninvasively and in vivo. Images are acquired with transcutaneous coherence probing depth up to 1.5 - 1.6 mm. Application of the optical clearing and direction sensitive OSV imaging to monitor the blood flow in the subcutaneous human blood vessels are discussed.
