In August of 2009 fNIR Devices, LLC started its operations after licensing various technologies from the estate of Dr. Britton Chance and the Drexel University.  fNIR Devices offerings, a line of Continuous Wave Functional Near Infrared imaging tools, are capable of monitoring brain’s hemodynamics and thereby the cognitive state of the subject in natural environments. fNIR technology employs specific wavelengths in an optical frequency window that can easily pass through a few centimeters for most tissues allowing monitoring of blood oxygenation changes. The relative changes of light intensity across time provide the researchers with information about neural activity.   Todate with over 250 brain imagers in the field, fNIR Devices is the premier supplier of fNIR Spectroscopy imaging systems for research and other non-clinical applications.
