Spectral Selective and Low‐Noise Thin‐Film Organic Photodetectors Enabled by Electric‐Field Engineering

Advanced Materials, EarlyView.
Molecular doping redistributes the internal electric field in organic photodetectors, providing a new degree of freedom to spatially control carrier transport and collection. Simulations and experiments reveal distinct transport pathways for injected and photogenerated carriers, enabling low dark current under reverse bias and wavelength‐selective ...

Synchronized Ablation of Multifocal Tumors Enabled by Multi‐Channel Lanthanide Nanocomposites

Advanced Materials, EarlyView.
A multi‐channel lanthanide nanocomposite enables orthogonal monitoring of tumor pH, glutathione, and temperature to guide customized therapy. Real‐time luminescence readouts determine a single irradiation protocol that synchronizes drug release and photothermal treatment, allowing efficient ablation of multifocal tumors while minimizing overtreatment ...

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

UC Food Waste: A Multimodal Robotic Perception Dataset for Robust Contaminant Detection in Complex Biowaste Scenes

Advanced Robotics Research, EarlyView.
A balanced multimodal food‐waste dataset and a novel Split Spatial‐Spectral Attention fusion framework are presented for robotic contaminant detection. Separate processing of RGB, thermal, and multispectral inputs preserves subtle material signatures before feature integration, reducing modality interference and improving classification and ...

Radiometric calibration and SNR calculation of a SWIR imaging telescope

AIP Conference Proceedings, 2012
Radiometric calibration of an imaging telescope is usually made using a uniform illumination sphere in a laboratory. In this study, we used the open-sky images taken during bright day conditions to calibrate our telescope. We found a dark signal offset value and a linear response coefficient value for each pixel by using three different algorithms ...

Evaluating textile wear using different optical imaging modalities [PDF]

EPJ Web of Conferences
This study evaluates textile wear using RGB camera, and VIS and SWIR hyperspectral imaging on abraded cotton samples. VIS (CIELAB coordinate b*) showed the strongest correlation with wear, and RGB (local binary pattern) and SWIR (PLS model) moderate ...
