There are two LDFs available for clinical application: the LD5000 Laser Doppler Perfusion Monitor and the Periflux Laser Doppler Flowmeter. Laser Doppler flowmetry is an optical measuring method that enables the number and velocity of particles conveyed by a fluid flow to be measured. The particles (1–20 μm) must be big enough to scatter sufficient light for signal detection but small enough to follow the flow faithfully ( Durst et al. 1976 , Durrani & Greated 1977 , Drain 1980 , Bonner & Nossal 1990 , Albrecht et al.

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.

Here the incident light in the red wavelength is incident upon the blood vessels. The red blood cells absorb the incident light and reflect light with a shifted frequency depending on the flow velocity. 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. Laser Doppler velocimetry is used in hemodynamics research as a technique to partially quantify blood flow in human tissues such as skin or the eye fundus. Within the clinical environment, the technology is often referred to as laser Doppler flowmetry; when images are made, it is referred to as laser Doppler imaging.
