High-contrast spectroscopic photoacoustic characterization of thermal tissue ablation in the visible spectrum [PDF]

open access: yesUltrasonography, 2023
Purpose High-contrast tissue characterization of thermal ablation has been desired to evaluate therapeutic outcomes accurately. This paper presents a photoacoustic (PA) characterization of thermal tissue ablation in the visible spectrum, in which higher ...

All-dielectric Schrödinger colours across the visible spectrum [PDF]

open access: yesNature Communications
Structural colours, which arise from nanostructures, are pervasive in nature and play a pivotal role in numerous modern applications. Traditional approaches usually deviate from the concept of Schrödinger’s pixels and thus have restricted performance in ...

Achromatic varifocal metalens for the visible spectrum [PDF]

open access: yesFrontiers in Optics + Laser Science APS/DLS, 2019
Metasurface optics provide an ultra-thin alternative to conventional refractive lenses. A present challenge is in realizing metasurfaces that exhibit tunable optical properties and achromatic behavior across the visible spectrum.

Carbon Dots Exhibiting Concentration-Dependent Full-Visible-Spectrum Emission for Light-Emitting Diode Applications

open access: yesACS Applied Materials & Interfaces, 2019
Carbon dots (CDs) that exhibit emission over the whole visible spectrum are desired for use in light-emitting diodes (LEDs). Here, CDs displaying tunable fluorescence over the whole visible region are synthesized.

What is light? The visible spectrum and beyond. [PDF]

open access: yesEye (Lond), 2016
In this International Year of Light, it is particularly appropriate to review the historical concept of what is light and the controversies surrounding the extent of the visible spectrum. Today we recognize that light possesses both a wave and particle nature.

Reconstructing Face Image from the Thermal Infrared Spectrum to the Visible Spectrum [PDF]

open access: yesSensors, 2016
During the night or in poorly lit areas, thermal cameras are a better choice instead of normal cameras for security surveillance because they do not rely on illumination.

Melamine Faced Panels Defect Classification beyond the Visible Spectrum [PDF]

open access: yesSensors, 2018
In this work, we explore the use of images from different spectral bands to classify defects in melamine faced panels, which could appear through the production process. Through experimental evaluation, we evaluate the use of images from the visible (VS),

Remotely piloted aircraft systems remote sensing can effectively retrieve ecosystem traits of alpine grasslands on the Tibetan Plateau at a landscape scale

open access: yesRemote Sensing in Ecology and Conservation, 2021
Ecosystem trait is a standardized description of biological features of a community, and it bridges individual plants and ecosystem. Conventionally most ecosystem trait data are collected from field survey and the generated data is hard to meet the ...
