Spectroscopy is the study of the interaction between radiation (electromagnetic radiation, or light, as well as particle radiation) and matter.

New brush optrode improves optical scanning of brain activity

One of the main techniques for measuring and monitoring mental activity, called functional near infrared spectroscopy (fNIRS), can often be impaired because a person's hair gets in the way. But now, thanks to a team of researchers at the University of Texas at Dallas and the University of Texas at Arlington, a novel device called a "brush optrode" is providing increased sensitivity with fiber tips designed to thread through hair to enhance scalp contact.
