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

High-contrast spectroscopic photoacoustic characterization of thermal tissue ablation in the visible spectrum [PDF]
Ultrasonography, 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]
Nature CommunicationsStructural 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 ...

Visible Spectrum Incandescent Selective Emitter [PDF]
, 2004 The purpose of the work performed was to demonstrate the feasibility of a novel bi-layer selective emitter. Selective emitters are incandescent radiant bodies with emissivities that are substantially larger in a selected part of the radiation spectrum, thereby significantly shifting their radiated spectral distribution from that of a blackbody ...

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

Eukaryotic algal phytochromes span the visible spectrum. [PDF]
Proc Natl Acad Sci U S A, 2014 Significance Photosynthetic organisms exploit photosensory proteins to respond to changing light conditions. In land plants, phytochromes use the ratio of red to far-red light to detect shading by neighboring plants, leading to changes in growth and development.
