Measurement of Velocity Gradient by Using Doppler Effect
Abstract
The general theory of a method for measuring velocity gradients in blood capillary flow using a laser Doppler microscope velocimeter is presented. When the distance between two incident beams at a certain plane x is known, the velocity gradient can be measured from the angular frequency of the output current (after optical-to-electrical conversion) by using a frequency tracker or wave-period measuring system for analyzing Doppler beat signals.
