Atmospheric scattering and turbulence modeling for ultraviolet wavelength applications
Bulletin of Atmospheric Science and Technology, 2020The recent proliferation of free-space optics (FSO) technologies and development of pertaining research have led to exploit the whole optical bandwidth from infrared and visible up to deep ultraviolet (UV) in communications. Within this context, we decided to focus on UV FSO communication and remote sensing potentials by presenting a physically based ...

Numerical model of the scattering of a gaseous and dispersed impurity in the atmosphere
Journal of Engineering Physics and Thermophysics, 2008A numerical model of the transfer of a gaseous and dispersed impurity in the atmosphere is described. The model is based on the semi-empirical stationary equation of turbulent diffusion in the boundary layer of the atmosphere with account for the gravitational deposition of particles.

Image Dehazing Algorithm Based on Atmosphere Scatters Approximation Model
2012Due to the scattered light of suspended particles in the atmosphere, the images taken in the foggy day become gray and are lack of visibility. In order to unveil the clear images structures and colors, the author propose an algorithm based on atmosphere scatters approximation model, which adopts the extended Jones Matrix and Stokes Law to calculate ...

Restoration of quality degraded image by atmospheric scattering model
2018 International Conference on Electronics, Information, and Communication (ICEIC), 2018The Quality of image is very important when we look at the image. Image quality is degraded by numerous factors when an image is taken. To compensate for degradation, constantly studying the improvement of image quality in image signal processing. In this paper, we propose a method for restoring the quality of images attenuated by the atmospheric ...

Model for the Atmospheric Fragmentation and Scattering of a Small Celestial Body
Combustion, Explosion and Shock Waves, 2005This paper considers the interaction of a small celestial body with a planetary atmosphere, which is treated as a two-stage process: the first stage is the fragmentation of the parental body (a model for this stage was developed by the authors) and the second stage involves breakup and scattering of the fragments.

Forming (NCCN)− by quantum scattering: A modeling for Titan’s atmosphere
Chemical Physics, 2012Abstract In the present paper we analyse in some detail the possible nuclear deformation paths which could lead, under the conditions observed in Titan’s atmosphere, to the formation of (NCCN) − stable anions following the interaction with low-energy electrons.

Intensity image restoration of lidar based on atmospheric scattering model
AOPC 2021: Optical Sensing and Imaging Technology, 2021In this paper, three algorithms are proposed to restore the fog-containing relative intensity image of lidar based on the atmospheric scattering model and dark channel prior theory. The algorithm was evaluated by analyzing the peak signal-to-noise ratio (PSNR) and structural similarity (SSIM) of the two data sets, including the fog-free relative ...

Stellar occultations by turbulent planetary atmospheres: A heuristic scattering model
Icarus, 1977Abstract A model of ray refraction by an isothermal atmosphere with a scattering screen at the center of bending is used to generate analytic results which simulate the effects of real atmospheric turbulence on occultations. Calculations are carried through for scattering which is constant with height and for exponential height dependence. The effect
