Synonyms Chemometrics in NIR spectroscopy ; NIR imaging ; NIR spectroscopy Definition This entry describes principle, instrumentation, analysis method (chemometrics), and biological applications of near-infrared (NIR) spectroscopy. Applications discussed include the studies of protein structure, denaturation ...
Near-infrared spectroscopy (NIRS) enables continuous, noninvasive bed-side monitoring ofoxygenation. As withpulse oximetry, it is based on the principle that the oxygen-carryingpigmentshemoglobin andcytochromeaa3have well-defined absorption spectra that are influenced by oxygen binding. NIRS technology th...
Near-infrared spectroscopy is based on the same principle as a pulse oximeter and allows continuous non-invasive monitoring of Hb oxygenation and deoxygenation and thus tissue saturation "StO2". These investigators provided an overview of NIRS technology principles and discussed its current clinical use...
Near-infrared spectroscopy (also referred to as near-IR spectroscopy or NIRS) is a spectroscopic technique that focuses its attention on the near-infrared region of the electromagnetic spectrum - 780 to 2500 nm. Video Credit: Metrohm Middle East FZC ...
Near-infrared spectroscopy (NIRS) has been widely used to evaluate the nutritional quality of agricultural products for several decades (Norris, 1996). It is based on the principle that infrared spectra contain quantitative information of functional groups; the energy absorbed by the covalent bonds of...
Basic Principle and Practical Implementation of Near-Infrared Spectroscopy (NIRS)Various brain-imaging techniques, such as CT, fMRI, and EEG, have been introduced with their own strength and weakness. While CT and fMRI systems are anything but portable and thus undermine their use in dynamic ...
NIRS principle is based on the use of near-infrared electromagnetic waves for qualitative and quantitative assessments of molecular factors related to tissue oxygenation. Although this technique can be apllied in any tissue, it is primarily used for monitoring peripheral oxygenation in the muscle. ...
近红外血糖无创检测原理及实现分析-principle and analysis of non-invasive detection of near infrared blood sugar.docx,摘要血糖无创检测研究的意义重大。糖尿病作为一种世界范围内的流行疾病,患者人数多,并以惊人的速度急剧增长。目前还没找到彻底根治糖尿病的方法,
We propose a near-infrared spectroscopy (NIRS)-based brain-computer interface (BCI) that can be operated in eyes-closed (EC) state. To evaluate the feasibility of NIRS-based EC BCIs, we compared the performance of an eye-open (EO) BCI paradigm and an EC BCI paradigm with respect to hemo...
