Laser doppler flowmetry (LDF) is a new non-invasive technique by which microcirculation changes in tissue can be studied. In recent papers, this technique has been used to measure microflow in standardized fluid models, in animals and in human clinical situations. Measuring with laser Doppler flowmeter. This instrument gives direct measurements of flow velocity for liquids containing suspended particles flowing in a transparent pipe. Light from a laser is focused by an optical system to a point in the flow, with fiber optic cables being commonly used to transmit the light. METHOD: A laser Doppler flowmeter was used to record relative blood flow to healthy gingiva and to forehead skin in smokers and non-smoking controls.

Blood perfusion (blood flow) is estimated by illuminating a tissue sample with single-frequency light and processing the frequency distribution of the backscattered light. Specifically for human studies, our single-channel Laser Doppler FlowMeter Laser Doppler Flowmetry Optical Imaging Based on Intrinsic Signals.

MedPacific LD 5000 laser Doppler flowmeter. Laser Doppler flowmetry of skin blood flow is based upon measurement of the Doppler frequency shift in monochromatic laser light which is backscattered from cutaneous tissue . The frequency shift is associated with velocity of moving particles within the tissue. Because the red cells are moving at
