Fusion of UAV hyperspectral and satellite multispectral data for quasi-hyperspectral data simulation and wetland land cover classification

Geo-spatial Information Science
Accurate wetland classification demands high spectral detail and large-area coverage – capabilities that neither satellite multispectral data (limited spectral resolution) nor unmanned aerial vehicle (UAV) hyperspectral data (limited spatial coverage ...

Opportunities of Semiconducting Oxide Nanostructures as Advanced Luminescent Materials in Photonics

Advanced Materials, EarlyView.
The review discusses the challenges of wide and ultrawide bandgap semiconducting oxides as a suitable material platform for photonics. They offer great versatility in terms of tuning microstructure, native defects, doping, anisotropy, and micro‐ and nano‐structuring. The review focuses on their light emission, light‐confinement in optical cavities, and

Comparison on quantitative inversion of characteristic ions in salinized soils with hyperspectral based on support vector regression and partial least squares regression

European Journal of Remote Sensing, 2020
This study aimed to investigate quantitative inversion of salt ions. Now, most research on hyperspectral characters in salinized soils focus on quantitative inversion of salt content, but few on ions.

High Light Utilization and Color Rendering in Vacuum‐Deposited Semitransparent Perovskite Solar Cells

Advanced Materials, EarlyView.
In this work, low bandgap (≈1.55 eV) semitransparent perovskite solar cells (ST‐PSCs) having thin (thickness < ≈100 nm) perovskite layers and transparent conductive oxide‐based rear electrodes are fabricated using vacuum‐deposition methods. Two different ST‐PSCs demonstrated a high light utilization efficiency value of 4.2 (PCE: 9.26% and AVT: 45.3 ...

Data inversion for hyperspectral objects in astronomy [PDF]

2009 First Workshop on Hyperspectral Image and Signal Processing: Evolution in Remote Sensing, 2009
We present an original method for reconstruction of hyperspectral objects (two spatial and one spectral dimensions) from data provided by the infrared slit spectrograph on board the Spitzer Space Telescope. The originality of the work lies in the fact that bothmeasurementmodel and inversionmethod are tackled in continuous (spatial and spectral ...

Micromachined Double‐Membrane Mechanically Tunable Metamaterial for Thermal Infrared Filtering

Advanced Photonics Research, Volume 6, Issue 5, May 2025.
Herein, a mechanically tunable double‐layer plasmonic metamaterial leveraging the extraordinary optical transmission effect observed in subwavelength arrays of openings within thin metal layers is presented. The concept is experimentally validated by integrating the proposed metamaterial structure into an electrostatic parallel‐plate actuator to create
