Meaning
Optical inhomogeneities within a medium cause the redirection of electromagnetic radiation when the particle size is comparable to the wavelength of the incident light. These mie scattering centers produce a characteristic distribution of light that is concentrated in the forward direction. The phenomenon differs from Rayleigh scattering because it depends heavily on the geometry and refractive index of the particles.
Particle Size
Measuring the intensity of the scattered light at various angles provides a way to calculate the diameter of suspended droplets or grains. Since mie scattering centers are often larger than the molecules of the surrounding fluid, they are visible as haze or turbidity in industrial liquids. Accurate modeling of this behavior is necessary for the production of paints and coatings.
It ensures that pigments achieve the desired opacity and color saturation.
Surface Finish
In the manufacture of high-purity glass and polymers, the presence of these defects can ruin the performance of a lens or optical fiber. Eliminating mie scattering centers requires precise control over the cooling rate and chemical composition of the melt. Even small concentrations of bubbles or inclusions can attenuate a signal over long distances.
Production Yield
The way light bounces off these particles allows sensors to monitor the quality of an aerosol or a smoke plume. Monitoring the density of mie scattering centers in a cleanroom environment helps maintain the standards required for semiconductor fabrication.
