Laser Doppler Flowometry

Doppler Effect analysis has proven to be a useful forensic tool for a variety of studies in physical and biological sciences. Having been used in fields varying such as astronomy, acoustics, vibrational analysis and flow research, it is now a major contributor to the advancement of research in biophysics and biomedical sciences. The objective of this paper is to provide a report of a technique known as Laser Doppler Flowometry (LDF) which uses relativistic doppler shift analysis to determine the velocity of particles suspended in a moving fluid. A direct application of LDF in medicine is in the field of hemodynamics research that seeks to quantify the flow of blood in human tissue. LDF is a highly favorable technique as it is noninvasive and is performed without causing a disturbance in the surrounding patterns of fluid flow or the tissue
