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 ...

Like infrared (IR) spectroscopy, Raman spectroscopy is a type of vibrational spectroscopy. These similar methods have some differing qualities, as IR bands emerge due to alterations in the dipole ...
