Basic LDV1 component system
Abstract
To measure one velocity component, the four different optical setups deduced from the theory of the Doppler effect are described; the most widely used 'fringe' LDV (Laser Doppler Velocimetry) is more detailed: signal to noise ratio evaluation, velocity sign determination, general structure of the emitting and receiving optics.
