Near-IR absorption spectrum of dichloromethane showing complicated overlapping overtones of mid IR absorption features. Near-infrared spectroscopy (NIRS) is a spectroscopic method that uses the near-infrared region of the electromagnetic spectrum (from 780 nm to 2500 nm). [1]
The Journal of Near Infrared Spectroscopy is a bimonthly peer-reviewed scientific journal published by SAGE Publishing in partnership with Optica.It was established in 1993 and covers near-infrared spectroscopy and its applications, with subtopics including chemometrics, chemical imaging, fiber optics, instrumentation and diffuse reflection.
Functional near-infrared spectroscopy (fNIRS) is an optical brain monitoring technique which uses near-infrared spectroscopy for the purpose of functional neuroimaging. [1] Using fNIRS, brain activity is measured by using near-infrared light to estimate cortical hemodynamic activity which occur in response to neural activity.
A VNIR image of the Ghadamis River in Libya.This is a false-color composite image made using near-infrared, green, and blue wavelengths. The visible and near-infrared (VNIR) portion of the electromagnetic spectrum has wavelengths between approximately 400 and 1100 nanometers (nm). [1]
Infrared spectrophotometer used to analyze the diethyltoluamide insect repellent, 1960 US Food and Drug Administration scientist uses portable near infrared spectroscopy device to detect potentially illegal substances. Infrared spectroscopy is a simple and reliable technique widely used in both organic and inorganic chemistry, in research and ...
Diffuse optical imaging (DOI) is a method of imaging using near-infrared spectroscopy (NIRS) [1] or fluorescence-based methods. [2] When used to create 3D volumetric models of the imaged material DOI is referred to as diffuse optical tomography, whereas 2D imaging methods are classified as diffuse optical imaging.
