Working visit to Neurophotonics Laboratory, University of California Davis, USA
The purpose of this business trip was to perform collaborative work on the interferometric near-infrared spectroscopy (iNIRS). More specifically, experiments to quantify optical properties in dynamic media were performed. Then, the data was processed numerically using the new method of correlation gating to separate ballistic and scattered light transmitted through thick samples. Given these components the optical properties of the dynamic medium from a single measurement were determined. Quantifying light transport in biological tissues and turbid media is an ongoing challenge. This challenge arises from the difficulty in experimentally separating unscattered, ballistic light from forward scattered light. Correlation gating is a new approach that numerically separates light paths based on statistical dynamics of the optical field. This method was applied to separate and independently quantify ballistic and scattered light transmitted through thick samples.
