WebThis paper describes a method of interpretation of unfiltered and filtered laser Rayleigh scattering (LRS and FLRS) in order to recover the temperature of flowing gases. WebRecently, Malischewsky [4] obtained a formula for the speed of Rayleigh waves for any range of values of γ by using Cardan’s formula together with trigonometric formulas for the roots of a cubic equation and MATHEMATICA. It is expressed as a continuous function of γ and contains a signum function, specifically sign(−γ+1/6).

"WebScattering of incident radiation occurs when the electrons are excited to unquantized virtual energy states and relax to a vibrational energy level. Since the incident radiation is not absorbed like in IR spectroscopy, most of the light scattered is unchanged and remains at the incident wavelength, termed Rayleigh scattering.
