Cerebral oximetry uses transcranial near-infrared spectroscopy (NIRS) to evaluate changes in cerebral oxygenation noninvasively and continuously. Its operation relies on two basic principles. First, near-infrared light has the capacity to penetrate human tissue, including bone. Second, in these tissues, hemoglobin is the predominant absorbing substance

Near-infrared Spectroscopy in the Brewing Industry
Critical Reviews in Food Science and Nutrition, 2012This article offers an exhaustive description of the use of Near-Infrared (NIR) Spectroscopy in the brewing industry. This technique is widely used for quality control testing of raw materials, intermediates, and finished products, as well as process monitoring during malting and brewing.

Near-Infrared Spectroscopy of Dark Asteroids
Icarus, 1994Near-infrared (J, H and K bands) spectra of nine dark asteroids (chosen among a sample of supposed primitive objects between C and D classes) have been obtained at the Mauna Kea Observatory (Hawaii) with the 2.2-m telescope using KSPEC as spectrograph.

Near‐infrared spectroscopy of polymers
Makromolekulare Chemie. Macromolecular Symposia, 1991AbstractAlthough near–infrared (NIR) spectroscopy has been used over many decades for the – primarily quantitative – analysis of polymers containing OH–, NH– and CH–functionalities (e.g. determination of OH–number, water content and residual carbon–carbon double–bonds), it has never been established as a wide–spread analytical and physical tool ...

In the near-infrared region the absorption process is associated with the overtone and combination bands of vibrational transitions. This region can be studied with the same equipment that is used for electronic spectra, apart from changing from photocell to photoconductive detectors above 1 µ.

In Vivo Near-Infrared Spectroscopy
Annual Review of Biomedical Engineering, 2000▪ Abstract Interrogation of tissue with light offers the potential for noninvasive chemical measurement, and penetration with near-infrared wavelengths (750–1000 nm) is greater than with visible light. Specific absorption by clinically relevant compounds such as oxy- and deoxyhemoglobin and the intracellular respiratory enzyme cytochrome oxidase ...

Interpretive Spectroscopy for Near Infrared
Applied Spectroscopy Reviews, 1996ABSTRACT Qualitative and quantitative near infrared spectroscopic (NIRS) methods require the application of multivariate calibration algorithms to model NIR spectral response to chemical or physical properties of a calibration sample set. The identification of unique wavelength regions where changes in the response of the near infrared spectrometer are
