3D infrared thermospectroscopic imaging [PDF]

Scientific Reports, 2020
AbstractThis work reports a multispectral tomography technique in transmission mode (called 3DITI for 3D Infrared Thermospectroscopic Imaging) based on a middle wavelength infrared (MWIR) focal plane array. This technique relies on an MWIR camera (1.5 to 5.5 μm) used in combination with a multispectral IR monochromator (400 nm to 20 μm), and a sample ...

Theoretical Investigation of Optical Intersubband Transitions and Infrared Photodetection in ${\beta}$-(AlxGa1-x)2O3/Ga2O3 Quantum Well Structures

, 2020
We provide theoretical consideration of intersubband transitions designed in the ultrawide bandgap Aluminum Gallium Oxide ((AlxGa1-x)2O3)/Gallium Oxide (Ga2O3)) quantum well system.

Transillumination imaging through scattering media by use of photorefractive polymers [PDF]

, 1998
We demonstrate the use of a near-infrared-sensitive photorefractive polymer with high efficiency for imaging through scattering media, using an all-optical holographic time gate. Imaging through nine scattering mean free paths is performed at 800 nm with

NICMOS Imaging of Infrared-Luminous Galaxies [PDF]

, 1999
We present near-infrared images obtained with the HST NICMOS camera for a sample of 9 luminous (LIGs: L_IR (8-1000 microns) >~ 10^11 L_sun) and 15 ultra-luminous (ULIGS: L_IR >~ 10^12 L_sun) infrared galaxies.

Ultrabroadband infrared nanospectroscopic imaging [PDF]

Proceedings of the National Academy of Sciences, 2014
Significance Through direct measurement of intrinsic vibrational and electronic modes, infrared spectroscopy provides label-free, chemical characterization of molecules and solids. The long micrometer-sized wavelength of infrared light, however, has limited the application of this widely applied spectroscopic technique to ensemble studies ...

Video-rate computational super-resolution and integral imaging at longwave-infrared wavelengths [PDF]

, 2017
We report the first computational super-resolved, multi-camera integral imaging at long-wave infrared (LWIR) wavelengths. A synchronized array of FLIR Lepton cameras was assembled, and computational super-resolution and integral-imaging reconstruction ...

Functional infrared imaging of the breast

IEEE Engineering in Medicine and Biology Magazine, 2000
In order to re-assess the potential contribution of infrared (IR) imaging as a first-line component of a multi-imaging strategy using currently available technology, we first review the history of its introduction and clinical application, including the results of the Breast Cancer Detection Demonstration Projects (BCDDP).

AEGIS: Infrared Spectral Energy Distributions of MIPS 70micron selected sources [PDF]

, 2006
We present 0.5 -160 micron Spectral Energy Distributions (SEDs) of galaxies, detected at 70microns with the Multiband Imaging Photometer for Spitzer (MIPS), using broadband imaging data from Spitzer and ground-based telescopes.
