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 ...

Infrared (IR) spectroscopy is suitable for qualitative analysis of initial polymer materials and end products. With this technique, components of polymer mixtures can be measured and in-process ...

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 ...
