Design of the Optical System for Exoscope-Based Videocapillaroscopy

Accurate monitoring of microvasculature functioning enables early detection of diseases related to skin microcirculation disorders. The efficient capillaroscopy approach is to visualize and assess blood microcirculation exactly in the inflamed areas. In this paper, we propose an exoscope concept for non-invasive imaging of capillary network in skin arbitrary area. The main design aspects are briefly discussed. The described concept has been approved experimentally by in vivo mapping and analysis of microvessels in human skin.
