Near-infrared Spectroscopy. Near-infrared spectroscopy (NIRS) has been widely utilized in food and feed, polymers and textiles since the 1980s, with other industries such as pharmaceuticals, personal ...

A research team from the Hefei Institutes of Physical Science of the Chinese Academy of Sciences has proposed a novel model optimization algorithm—External Calibration-Assisted Screening (ECA)— that ...

Near-infrared spectroscopy is a form of non-invasive imaging that applies near-infrared radiation (wavelengths 780 nm to 3,000 nm) to chemicals or biological subjects to measure differential ...

Infrared spectroscopy can probe the conditions and compositions of exoplanet atmospheres. Previous results relied on space-based telescopes that do not provide spectroscopic capability in the 2.4 ...

ABSTRACT An atlas of a thorium‐argon hollow cathode lamp in selected intervals of the 1–2.5 μm region is presented. Accurate wavelengths of the ∼500 lines recorded are given in a table. This material ...

The near infrared spectrum runs the range of wavelengths 800 - 2500 nm, and is therefore just below the region of visible light but above the usual mid-infrared, at 2,500 - 30,000 nm.

Near-infrared spectroscopy (NIRS) is a noninvasive method used to monitor changes in hemoglobin concentration and oxygen levels in the body. This technique involves passing near-infrared light ...

Near-IR spectroscopy (NIRS) is the attractive approach to monitoring the optical and dynamic properties of the human brain, able to measure blood oxygen saturation and the concentrations of oxy- and ...
