Abstract

Laser-Doppler flowmetry is sometimes referred to as an art. Such an expression indicates that besides the instrument itself, a number of precautions must be considered in order to use the method properly. Therefore, this chapter reviews some important practical precautions regarding the use of laser Doppler flowmetry. It also describes some innovations and modifications that have been made to laser-Doppler flowmeters and flow probes.
