Interferometric diffuse correlation spectroscopy (iDCS) is an emerging technique that enables high quality measurements of cerebral blood flow. By including a reference arm in the optical setup, the SNR of the measured signals are improved relative to traditional DCS. We report here an expansion of our previously demonstrated 1064 nm single channel line scan camera based iDCS system to a multi-source, multiple detection channel approach to enable imaging of the brain perfusion response to functional activation. We confirm the ability to image multiple detectors on a single camera with minimal cross-talk using phantom experiments and show initial functional imaging results.
