It occursbecausethe waves emittedbythe source A laser Doppler perfusion imaging technique based on dynamic light scattering in tissue is reported. When a laser beam sequentially scans the tissue (maximal area approximately 12 cm*12 cm), moving blood cells generate Doppler components in the backscattered light.

Recording of tissue perfusion is important in assessing the influence of peripheral vascular diseases on the microcirculation. This thesis reports on a laser Doppler perfusion imager based on dynamic light scattering in tissue. When a low power He-Ne laser beam sequentially scans the tissue,

Laser Doppler measurements of blood flow in capillary tubes and retinal arteries. Wårdell, K. Laser Doppler perfusion imaging – methodology and skin

Laser Doppler imaging (scanning laser Doppler) LDF offers continuous perfusion measurement. However, cutaneous circulation is known to be heterogeneous, and examining a small area of perfusion does not necessarily give representative data for the surrounding perfusion [ 16 ]. Laser Doppler perfusion imaging (LDPI) is a noninvasive and relatively new technique for measuring skin blood perfusion. The development of laser Doppler perfusion imaging devices that estimate tissue perfusion by scanning an area of tissue using a laser may overcome the problem of signal calibration (Wardell et al, 1993).
