The effects of cooling of a hand on lateral and contralateral digital skin blood flow were investigated in 18 patients with primary or secondary Raynaud's phenomenon. The aim of the study was to compare photoelectrical plethsmography (PhEP) and laser

Fluid flow in a flow model was measured with a laser Doppler flowmeter normally used for tissue perfusion measurements. The flow parameter is deduced from the first moment of the spectral power density of intensity fluctuations at a detector viewing

Reactive hyperaemia, which occurs after a period of arterial occlusion is the result of an autoregulatory mechanism, involving local factors and autonomic nerve system control. To determine this autoregulatory mechanism in cutaneous blood flow in pre

A very small and simple velocimeter is presented consisting of a diode laser with a gradient-index lens in front of it. The basis of the velocity measurement is the mixing that occurs when light, scattered back by the moving object into the laser cav

A perfusion sensor was constructed by integrating a diode laser, two photodiodes and two current-voltage convertors in a small (diameter 17 mm and height 13 mm) and light (6 grams) probe. The perfusion is determined from intensity fluctuations on the

In their report on laser Doppler flow measurements (J. Biomed. Eng. 1985, 7, 225) Boggett et al. compared, among other things, three different light sources for use in a laser Doppler device. The aim of that study was to distinguish between Doppler s
