Rayleugh scatter filter

WebThe type of scattering responsible for this is called Rayleigh scattering and occurs when the particle doing the scattering is much smaller than the wavelength of radiation being scattered. An incoming wave is absorbed by the particle and another wave of the same wavelength is reemited in a variety of directions, or "scattered". WebThe post-processing of filtered Rayleigh scattering images has been made more effective by reducing the presence of particles using a digital particle rejection filter. Finally, a theoretical analysis was conducted on the simultaneous presence of Rayleigh and Mie scatter in order to improve experimental design of filtered Rayleigh scattering.
