BVIFormer: a binocular-vision-inspired transformer with binocular competitive fusion for single-image restoration [PDF]

open access: yesScientific Reports
Human vision remains robust in adverse weather by combining foveated processing with binocular integration. Inspired by this mechanism, we propose BVIFormer, a binocular-vision-inspired Transformer for single-image restoration.

Atmospheric Research for Adaptive Optics

open access: yesAtmospheric and Oceanic Optics, 2022
Abstract Adaptive optics (AO) systems are an essential part of large astronomical telescopes and laser complexes operating through the atmosphere. Each AO system is individually designed; the requirements for the components and the performance of an AO system are determined by the intensity and distribution of ...

Relative sky radiance from multi-exposure all-sky camera images [PDF]

open access: yesAtmospheric Measurement Techniques, 2021
All-sky cameras are frequently used to detect cloud cover; however, this work explores the use of these instruments for the more complex purpose of extracting relative sky radiances. An all-sky camera (SONA202-NF model) with three colour filters narrower

Light Backscattering by Ice Crystals of Cirrus Clouds Within the Physical Optics Approximation [PDF]

open access: yesEPJ Web of Conferences, 2020
Lidar technologies are widely used for retrieving microphysics of cirrus clouds, i.e. sizes, shapes and spatial orientation of ice crystals constituting the clouds. Interpretation of the lidar signals are based on the backscattered light.

The Depolarization Properties of Cirrus Cloud by Lidar: Observation and Model Match [PDF]

open access: yesEPJ Web of Conferences, 2020
The Polarization Lidar has been developed for cirrus cloud optical properties measurement. The Nd-YAG laser is employed as emitting linear source and two channels are used for detecting back-scattering signals from cirrus cloud including two 532 nm ...

Estimation of the cross-wind speed from turbulent fluctuations of the image of a diffuse target illuminated by a laser beam

open access: yesКомпьютерная оптика, 2022
The article presents an optical method for assessing the transverse wind, based on the analysis of turbulent distortions of the image of a diffuse target illuminated by a laser beam. The proposed correlation algorithm for processing video images allows
