Abstract

A new laser Doppler blood flowmeter for measuring skin perfusion is presented. The flowmeter consists of a probe that uses two different wavelengths and is able to measure at different depths. It may be used to distinguish the superficial microcirculation of the skin providing nutritional flow and the flow in deeper situated blood vessels (thermoregulatory flow). Measurements and Monte Carlo simulations of the Doppler signals for human skin are shown.
