Optical measurement of characteristics of thin films using a spiral zone plate

Компьютерная оптика
In this work we propose a method for measuring physical characteristics of thin samples (thin films), including thickness, refractive index and tilt by moving the observation plane.

Image-Dehazing Method Based on the Fusion Coding of Contours and Colors

IEEE Access, 2019
The dehazing of images shot in fog is a hot spot in the study of computer vision. Unlike dehazing methods, which use an atmospheric scattering model, the method proposed here is based on fusion coding of contours and colors.

Quantifying the Robustness of Vegetation Indices through Global Sensitivity Analysis of Homogeneous and Forest Leaf-Canopy Radiative Transfer Models

Remote Sensing, 2019
Vegetation indices (VIs) are widely used in optical remote sensing to estimate biophysical variables of vegetated surfaces. With the advent of spectroscopy technology, spectral bands can be combined in numerous ways to extract the desired information ...

Canopy imaging spectroscopy reveals a stepwise redshifted energy redistribution in the antenna under drought stress

Scientific Reports
There is a consensus on the role of protein conformational changes within the photosynthetic antenna that alter the spectral properties of the embedded pigments during regulated heat dissipation, but despite this, the molecular mechanisms involved are ...

Detection of elliptical polarization parameters using a metalens

Компьютерная оптика
A metalens capable of detecting the polarization ellipticity of an incident beam is considered in this paper. This metalens consists of blocks with diffraction gratings of a 140-nm height and a 220-nm period.

Fourier-invariant autofocused Laguerre-Gaussian beams

Компьютерная оптика
We study a new Laguerre - Gaussian (LG) beam, which differs from conventional LG mode beams that preserve the structure of the intensity distribution up to scale.
