In 1988 Prof. Randall L. Barbour & Prof. Ray Aronson, the founders of NIRx, introduced the concept of tomographic imaging (i.e., multi-distance spectroscopic measurements) in dense scattered media based on diffusely scattered light. This approach has since been widely adapted and has served to launch the modern day field of fNIRS tomography.

One of the key advantages of NIRS imaging is the ability to measure more than one participant at a time in a dynamic environment.  Furthermore, subjects can be moving quite a lot, so long as your NIRS setup has been done properly.  NIRx systems use a variety of components to minimize motion artifact and ensure top signal quality. 

fNIRS-based BCI for Robot Control

This video shows real-time control of a simple robot using just the brain: the NIRx NIRS system and an EEG system is used to record the brain's signal, which is then analyzed in real-time to determine the direction to send the robot.
