| Normal fibre separations in the probe head are a few tenths of 1mm, consequently blood flow is measured in a tissue volume of typically 1mm3 or smaller.
(Fig.1.8.a)
(Basic Theory and Operating Principles of LDF & LDI, Moor instruments Ltd User manual, 2003) In a Laser Doppler blood flow Imager (LDI) the low intensity laser beam is scanned across a tissue surface in a raster fashion using a moving mirror. There is no direct contact with the tissue being assessed. The basic elements of the moorLDI are shown schematically in the following figure. (Fig.1.8.b)
