Automatic scanner for multi-point laser Doppler flux recordings on human skin.
A computer-driven device is described which moves the probes of a laser Doppler flowmeter linearly back and forth over the skin and stops precisely at preselected points to measure capillary perfusion. It offers extended possibilities to record the spatio-temporal flux changes in response to a local stimulus (e.g. injection of a vasoactive substance).
