Abstract

We utilized a CMOS (Complementary Metal Oxide Semiconductor) video-camera for fast flow imaging with use of the laser-Doppler technique. A single sensor is used for both observation of the area of interest and measurements of the interference signal caused by dynamic light scattering from moving particles inside scattering objects. Particularly we demonstrate the possibility to image the distribution of the moving read blood cell concentration. This is a first step towards laser Doppler imaging without scanning parts, leading to a much faster imaging procedure compared to existing mechanical laser Doppler perfusion imagers.
