MULTIRESOLUTION IMAGE FUSION: PHASE CONGRUENCY FOR SPATIAL CONSISTENCY ASSESSMENT

, 2010
Multiresolution and multispectral image fusion (pan-sharpening) requires proper assessment of spectral consistency but also spatial consistency. Many fusion methods resulting in perfect spectral consistency may leak spatial consistency and vice versa ...

Improving Digital Mapping of Soil Organic Carbon and Total Nitrogen Through Integration of Sentinel‐1 Backscatter, InSAR Coherence, and Sentinel‐3 OLCI/SLSTR Observations

Land Degradation &Development, EarlyView.
ABSTRACT The potential of optical satellites for the spatial prediction of soil organic carbon (SOC) and total nitrogen (STN) has long been recognized. Owing to their balanced spatial–temporal resolution, multisource observational capabilities, and unprecedented availability of free data, Sentinel satellites offer unique opportunities for mapping soil ...

Responsive Phase Gradient Metasurface for Laser Stealth and Dynamic Thermal Camouflage

Laser &Photonics Reviews, EarlyView.
The graphical abstract depicts a phase‐gradient metasurface enabling directional scattering and emissivity‐controlled thermal radiation. The engineered phase profile redistributes the reflected optical momentum, suppressing specular reflection and generating non‐specular scattering.

Multispectral Concentric Grafted Perfect Vector Vortex Beam

Laser &Photonics Reviews, EarlyView.
Multispectral structured light offers powerful opportunities for increasing information capacity. A multispectral concentric grafted perfect vector vortex beam is proposed to engineer topological charges and polarization. A metasurface can graft different perfect vector vortex beams across concentric spatial regions and extend this concept to ...

Interleaved Diffractive Networks for Information Transfer Through Random Diffusers

Laser &Photonics Reviews, EarlyView.
This work presents a cascaded diffractive optical network that enables information transfer through random, unknown diffusers using passive, interleaved structured layers that mitigate scattering without digital computation. A hybrid optical‐digital version further improves robustness and reconstruction fidelity under distortions, with both simulations
