WebThe Rayleigh criterion for resolution is met when the maximum intensity of one point spread function overlaps the first minimum of the other. For two points emitting at the same wavelength, this separation distance corresponds to the radius (or peak-to-minimum distance) of the central bright region of a single point spread function. http://plaza.ufl.edu/dwhahn/Rayleigh%20and%20Mie%20Light%20Scattering.pdf

WebThe Rayleigh-Index is computed for a three-dimensional domain based on analytical flame transfer functions for experimentally obtained data of OH*-chemiluminescence as measure for the spatial heat release. Two models from different sources are applied, which describe the interaction between flame and acoustic locally. WebRayleigh Scattering If the particles are small compared to the wavelength of the laser used (typically less than d ª 10 or around 60nm for a He-Ne laser), then the scattering from a particle illuminated by a vertically polarised laser will be essentially isotropic, i.e. equal in all directions. The Rayleigh approximation tells us that d6 and ... can bad sleeping position cause chest pain
