IR spectroscopy, or infrared spectroscopy, is an analytical technique used to identify and study chemical substances based on their interaction with infrared radiation. It measures the absorption of ...

Infrared spectroscopy (IR spectroscopy) is an optical technique that detects molecular bond vibrations and rotations upon absorption of infrared light. Because different chemical functional groups ...

Researchers demonstrate critical improvements to functional Near Infrared Spectroscopy (fNIRS)-based optical imaging in the brain. In an article published today in the peer-reviewed, open-access SPIE ...

IR spectroscopy allows studying large sample areas with very high local resolution. A new detection system examines all points on the image simultaneously, ensuring average measuring time of only a ...

Infrared spectroscopy (IRS) is a technique used to analyze individual substances in isolation or a mixture, using their spectral information. IRS is based on the measurement of the wavelength and ...

The innovative methodology, reported in the SPIE journal Neurophotonics, shows that using frequency domain measurement in functional neuroimaging improves quality as well as depth resolution ...
