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 ...

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 ...
