Extracranial contamination has a significant effect on near-infrared spectroscopy measurements of cerebral oxygen saturation, according to a study published in the April issue of Anesthesiology.

The PbS QD filter array coupled with an InGaAs image sensor forms a high-performance NIR computational spectrometer capable of distinguishing materials and measuring alcohol content with high accuracy ...

Coupling mid-infrared “idler” photons with near-infrared “signal” photons enables cheaper, smaller and more efficient machines for uses such as greenhouse gas monitoring to medical diagnostics.

Near-infrared spectroscopy, known as NIR spectroscopy or NIRS, is a long-established analytical technique. For over 30 years, it has proven to be a fast and reliable method for measuring chemical and ...
