Cavity-enhanced Rayleigh scattering [PDF]

open access: yesCLEO/Europe - EQEC 2009 - European Conference on Lasers and Electro-Optics and the European Quantum Electronics Conference, 2009
We demonstrate Purcell-like enhancement of Rayleigh scattering into a single optical mode of a Fabry-Perot resonator for several thermal atomic and molecular gases. The light is detuned by more than an octave, in this case by hundreds of nanometers, from any optical transition, making particle excitation and spontaneous emission negligible.

Measurement of Temperature-Dependent Bulk Viscosities of Nitrogen, Oxygen and Air From Spontaneous Rayleigh-Brillouin Scattering

open access: yesIEEE Access, 2019
In this paper, the spontaneous Rayleigh-Brillouin scattering spectra of air are simulated to study the effect of uncertainties of pressure, temperature, scattering angle and the characteristic parameter uncertainty of the Fabry-Perot interferometer on ...

Theoretical analysis of backscattering in hollow-core antiresonant fibers

open access: yesAPL Photonics, 2021
We present a theoretical analysis into the fundamental physical mechanisms contributing to backscattering in hollow-core antiresonant fibers. We consider Rayleigh scattering originating from the hollow regions of the fiber, which may be filled with gases,

A Fast Single-Image Dehazing Algorithm Based on Dark Channel Prior and Rayleigh Scattering

open access: yesIEEE Access, 2020
The scattering of atmospheric particles significantly alters images captured under hazy weather condition. Images appear distorted, blurry and low in contrast attenuation, which extensively affects computer vision systems.

In-Flight Calibration of GF-1/WFV Visible Channels Using Rayleigh Scattering

open access: yesRemote Sensing, 2017
China is planning to launch more and more optical remote-sensing satellites with high spatial resolution and multistep gains. Field calibration, the current operational method of satellite in-flight radiometric calibration, still does not have enough ...

Parameter optimization for Rayleigh–Mie lidar under different dust conditions for the landing area of Martian Tianwen-1

open access: yesEarth and Planetary Physics
Mars is the terrestrial planet in the solar system that is closest to the Earth. Studying the atmospheric parameters of Mars and studying the evolutionary history of the Martian environment on this basis is helpful for people to discover signs of ...

Non-Rayleigh scattering behavior for anisotropic Rayleigh particles [PDF]

open access: yesOptics Letters, 2012
Derived from the light scattering by a radially anisotropic sphere, unusual scattering behavior is exhibited, which breaks the Rayleigh law (scattering efficiency Q(sca)~q(4) as q→0, where q is the size parameter). Under certain conditions, we demonstrate an asymptotical relation between Q(sca) and q, i.e., Q(sca)=Fq(8), which is not realizable for ...

Accuracy of radar-based precipitation measurement: An analysis of the influence of multiple scattering and non-spherical particle shape

open access: yesEarth and Planetary Physics, 2018
Two assumptions are typically made when radar echo signals from precipitation are analyzed to determine the micro-physical parameters of raindrops: (1) the raindrops are assumed to be spherical; (2) multiple scattering effects are ignored.
