Near-infrared spectroscopy is a new technique for noninvasive monitoring of tissue oxygenation and hemodynamics. Until now, it has been used solely for research into the physiopathology of the brain. This technique offers considerable untapped potential for research and clinical applications.

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.

Functional near-infrared spectroscopy
IEEE Engineering in Medicine and Biology Magazine, 2006The purpose of the this article is to describe an emerging neuroimaging technology, functional near-infrared spectroscopy (fNIRs), which has several attributes that make it possible to conduct neuroimaging studies of the cortex in clinical offices and under more realistic, ecologically valid parameters.

Journal of Near Infrared Spectroscopy, 1998
Some of the concepts that make a near infrared spectrum understandable are reviewed. The origin of vibrational anharmonicity which determines the occurrence and the spectral properties (frequency, intensity) is discussed. The importance of the effects of the resonances which increase with increasing excitation are mentioned.

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.
