Light propagation in a model for blood perfusion in tissue was simulated with Monte Carlo calculations to investigate the dependence of the output of laser Doppler perfusion meters on the configuration of the optical probe and on the multiple scatter

A differential laser Doppler anemometer (LDA) of NLR and a laser-two-focus (L2F) anemometer of DLR were selected to be installed in a research aircraft to demonstrate their capabilities for in-flight flow investigations. A ground test with the anemom

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

Changes in forehead skin blood flow were determined in 17 healthy, term newborns, using a fiberless diode laser Doppler flow meter (Diodopp). Measurements were carried out three times on each infant, at postnatal ages of 16.8 +/- 7.4 h, 58.9 +/- 6.2

Measurements are presented of two-phase counterflow phenomena in a 4 He-circulating dilution refrigerator. In order to make filmshots of these phenomena the measurements are performed in a refrigerator entirely made out of glass. Recording is done us

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
