Light scattering small particle

When a beam of light strikes small particles in its path, the light is said to be scattered the particles send off the light incident on them in many directions. Part of a beam incident on a translucent material, for example.

The full extinction Cext will be observed only if the detector subtends a sufficiently small solid angle. As the detector is moved closer to the particle, however, the observed extinction will decrease. We shall see when we consider specific examples that light scattered by particles much larger than the wavelength of the incident light tends to be concentrated around the forward direction. Therefore, the larger the particle, the more difficult it is to exclude scattered light from the detector. 

Another type of intrinsic property is derived from the theory of light scattering in particles. The phenomenon of Raman and fluorescent scattering from molecules suspended in small dielectric particles exemplifies such prop-...

This is based on the principle of light scattering of particles as a function of their hydrodynamic radius. Commonly used, as it requires a small sample size and is a rapid method for particle size measurement. It can be used to measure particles varying in size from 0.001 to 100pm.
