Abstract

We developed and applied parallel interferometric near-infrared spectroscopy (πNIRS) to noninvasively monitor pulsatile blood flow deep into the human tissue in vivo. With the unique capability of accessing complex information (amplitude and phase) about the sample with more than 1000 parallel channels, we can sense blood flow with only 20 ms integration time, making the πNIRS one of the fastest and comprehensive diffuse optical method.
