What is the temporal resolution of NIRS?

The temporal resolution of an fNIRS device depends on its hardware as well as how its individual channels operate with respect to one another. Through time-multiplexing of the source firing, some systems can achieve anywhere between 3-25Hz depending on the optode montage. For a particular application, scan speed can be traded off against the desired coverage area (field-of-view) or source density (image resolution).
