本文研究了激光多普勒血流速度计记录皮肤血流时的纤维运动伪影问题。对于静止目标、未加热的皮肤、加热的皮肤（43.5 ° C）、和未加热的皮肤，获得拍频频谱。C），对于各种诱导的纤维运动量，有和没有血流阻塞。考虑了消除纤维运动伪影或获得纤维运动伪影指标的可能方法。所提出的解决方案是结合在换能器内终止的附加纤维，以允许获得与血流无关的纤维运动指数。
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.degree. 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.
