Laser Doppler velocimetry , även känd som laser Doppler anemometri , är tekniken att använda Doppler-förskjutningen i en laserstråle för att mäta hastigheten i transparenta eller halvtransparenta vätskeflöden eller den linjära eller vibrerande rörelsen av ogenomskinliga, reflekterande ytor.
The aim of this investigation was (1) to evaluate the reliability of laser Doppler flowmetry (LDF) taking into consideration the use of a silicone splint and the inclination of the probe towards the buccal surface of a human tooth and (2) to determine whether diurnal variations of pulpal blood flow …
Other advantages are that the speed measurement is absolute and does not require any calibration curve of the instrument. The cost of this technology is still very high , effectively limiting its use to very particular applications. Laser Doppler flowmetry (LDF) is a method used to assess blood flow in microvascular systems. Attempts are being made to adapt this technology to assess pulpal blood flow. A diode is used to project an infrared light beam through the crown and pulp chamber of a tooth. The infrared light beam is scattered as it passes through the pulp tissue.

Laser Doppler perfusion monitoring measures the total local microcirculatory blood perfusion including the perfusion in capillaries (nutritive flow), arterioles, venules and shunting vessels. The definition of perfusion is the concentration of red blood cells times their average velocity.
Quantitative Laser Doppler Flowmetry -x-medelhöga, respektive höga hastigheter. Dessutom ges detta flödesmått som medelvärdet av flödet i en 3 mm3 stor volym som har formen av en halvsfär. Metoden har använts för att studera de mikrocirkulatoriska förändringar som inträffar vid diabetes typ 2, så kallad åldersdiabetes.
