Abstract

A mini laser-Doppler instrument for monitoring capillary flow or flow in tubes, in which a small solid state laser and two photodiodes are integrated in the probe, is described. The instrument is meant for use with skin or arterial blood flow. The mean Doppler frequency derived from the normalized first moment of the frequency distribution, measured with this instrument, appears to be linearly dependent on the flow velocity in the 0–2-mm sec⁻¹ region.
