NIR spectroscopy concerns the analysis of how NIR light and matter interact. In spectroscopic analysis, light is determined by the wavelength, not by the applied energy. The wavelength of light is ...

FTIR deals with the infrared region of the electromagnetic spectrum, and it works by measuring how much light is absorbed by the bonds of vibrating molecules to provide a molecular fingerprint. The ...

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 ...

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 ...
