Schematic representation of Raman spectroscopy. After the sample (molecule) is exposed to an intense beam of monochromatic light in the frequency range of visible, near-infrared or near-ultraviolet ...
Functional near-infrared spectroscopy, or fNIRS, measures changes in metabolic activity. It does this by passing infrared light through the skull to monitor blood flow. Both methods can monitor ...
Definition: Fourier Transform Infrared (FTIR) Spectroscopy is a highly specialized type of IR spectroscopy. It's the most common way IR measurements are carried out today. FTIR is known for its speed, ...
The strategy involves imaging methods-;called hyperspectral near-infrared spectroscopy and diffuse correlation spectroscopy-;commonly used at the bedside to monitor tissue conditions. In ...
SEIRA spectroscopy amplifies molecular vibrational signals by utilizing the infrared near-field enhancement provided by rough metal surfaces or metallic nanostructures. Its primary advantage is ...
