The focus region or waist is positioned within the fluid flow which contains natural or seeded reflective particles. The natural coherence of the laser beam generates a series of linear interference fringes in the area it is recombined.
Particles passing through the beam waist reflect the light which is refocused into a photodetector and measured. The intensity of the reflected light varies due to the Doppler shift caused by the difference between incident and reflected light, and is therefore proportional to the velocity of the fluid passing through the beam.
