Interferometric near-infrared spectroscopy (iNIRS)

Definition: A time-of-flight (TOF) resolved sensing technique used to identify the optical and dynamical characteristics of a turbid medium. This is measured by the interference pattern from the spectrum of light traversing the medium with a rapidly tunable or frequency-swept light source. The performance of the iNIRS system depends on the spectral and tuning parameters of the light source, with the spectral linewidth determining the TOF range, while the bandwidth determines the TOF resolution.
