The Near-Infrared Coronal Spectrum
The Astrophysical Journal, 1996Sensitive measurements of the near-infrared coronal spectrum were obtained from the 1994 total solar eclipse. A new [S IX] emission line at 1.25249 ± 0.00003 μm has been detected, and a bright, potentially important diagnostic, [Si X] line at 1.43 μm has been confirmed.

Atmospheric optics in the near infrared
Applied Optics, 2017Digital near-infrared photography opens up new observation possibilities and applications for atmospheric optics. We discuss necessary conditions and requirements for observing a variety of atmospheric optical phenomena in the infrared spectral range and report for the first time near-infrared photographs of 22° ring halos and inferior mirages.

Near-infrared oximetry of the brain
Progress in Neurobiology, 1999Near-infrared (IR) light easily penetrates biological tissue, and the information offered by in vivo spectroscopy of cerebral oxygenation is detailed and comes with a high temporal resolution. Near-IR light spectroscopy (NIRS) reflects cerebral oxygenation during arterial hypotension, hypoxic hypoxaemia and hypo- and hypercapnia.

Near infrared imaging with nanoparticles
WIREs Nanomedicine and Nanobiotechnology, 2010AbstractNear infrared imaging has presented itself as a powerful diagnostic technique with potential to serve as a minimally invasive, nonionizing method for sensitive, deep tissue diagnostic imaging. This potential is further realized with the use of nanoparticle (NP)‐based near infrared (NIR) contrast agents that are not prone to the rapid ...

Near‐Infrared Chemiluminescent Theranostics
Angewandte ChemieAbstractMolecular chemiluminescence probes with near‐infrared (NIR) emission offer promising benefits in deciphering complex pathological processes in a living system, as NIR chemiluminescence minimizes autofluorescence, enhances deep‐tissue penetration, and improves signal‐to‐noise ratio.

Understanding Near-Infrared Spectroscopy
Advances in Neonatal Care, 2011Near-infrared spectroscopy (NIRS) is a noninvasive technique that monitors regional tissue oxygenation reflecting perfusion status. Near-infrared spectroscopy has the ability to continuously and simultaneously monitor tissue perfusion in different organ systems at the bedside without interrupting routine care.

Near InfraRed Imagery Colorization
2018 25th IEEE International Conference on Image Processing (ICIP), 2018This paper proposes a stacked conditional Generative Adversarial Network-based method for Near InfraRed (NIR) imagery colorization. We propose a variant architecture of Generative Adversarial Network (GAN) that uses multiple loss functions over a conditional probabilistic generative model.

Glory of clouds in the near infrared
Applied Optics, 1994Spectrally resolved visible and infrared images of marine stratus clouds were acquired from the NASA ER-2 high-altitude aircraft during the 1987 First International Cloud Climatology Program Regional Experiment. The images were obtained by cross-track scanning radiometers.
