Effect of different scattering function anisotropy factors on look of atmospheric scattering and fog can be seen on following screenshots (progressively larger anisotropy). WebMie Scattering. Scattering by spherical particles. This is the simplest type of scattering, since two of the scattering coefficient must identically equal zero due to symmetry. The formal rigorous solution is usually attributed to Gustav Mie (1908). Although the solution to the sphere problem appears to been attained previously, Mie was the ...

WebThe scattered light intensity in Rayleigh scattering for unpolarized light is proportional to (1 + cos 2 s) where s is the scattering angle, i.e. the angle between the directions of the incident and scattered rays. Scattering by Aerosols Scattering by aerosol particles depends on the shapes, sizes and the materials of the particles. Web3.2. Mie Scattering If the particles are of similar size or a bit larger than the wavelength, the Rayleigh approximation can not be used. The scattering of spherical particles can be solved analytically, and is called Mie Scattering af-ter Gustav Mie (18-69-1957) the ﬁrst to publish the solution.

WebMIe scattering is also the more appropriate model compared to Rayleigh scattering when the particle size is larger than around 10% of the wavelength of the incident radiation. Accordingly, the minimum particle radius for MIe scattering to be valid is around 0.1 μm given the longest laser wavelength considered in our work, which is 1.064 μm .
