3. Particle description
-
The simplest form is spherical. The particle's size is then described by a single length (its radius r or diameter d). In light scattering, the size parameter is used instead:
where the diameter is scaled by the wavelength.
Rayleigh and geometrical optics theories are obtained for the limits

Many conferences are dedicated to optical measurement techniques, in particular laser velocimetry. The proceedings invariably include papers dedicated to light scattering, in particular the phase-Doppler technique. The most famous of these is probably "The International Symposium on Applications of Laser Techniques to Fluid Mechanics", held biannually in Lisbon since 1982.

Manufacturers
Many researchers build their own laser-Doppler velocimeters or phase-Doppler granulometers, for reasons of economy and/or to exercise greater control over the instrumentation, or even to adapt it to specific conditions
