Laser Doppler Flowmetry

Laser Doppler flowmetry (LDF) is a non-invasive method for the continuous measurement of microvascular blood perfusion in a variety of tissue types. 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 can be used with a specialized fiber optic probe to measure relative changes in skin perfusion in response to vasoactive drugs, or to record and measure non-invasive blood flow within a microvascular bed.
