Laser Doppler velocimetry: the problem of fibre movement artefact
J Biomed Eng.
1987 Apr.
Abstract
The problem of fibre movement artefact in laser Doppler velocimetry recordings of skin blood flow has been investigated. Beat frequency spectra were obtained for a stationary target, unheated skin, heated skin (43.5 degrees C), with and without blood flow occluded for various induced amounts of fibre movement. Possible methods for either eliminating, or obtaining an indicator of, fibre movement artefact were considered. The solution proposed is to incorporate additional fibres terminating within the transducer to permit an index of fibre movement to be obtained that is independent of blood flow.
