159th seminar of the International Center of Biocybernetics: Optics in Neuromonitoring
The aim of this visit was to participate in the 159th seminar of the International Center of Biocybernetics: Optics in Neuromonitoring, where Dawid Borycki delivered the talk entitled as: Monitoring time-of-flight-resolved temporal dynamics of optical field using interferometric near-infrared spectroscopy (iNIRS). The short abstract of this presentation is below.
Intensity fluctuations of light scattered from a turbid medium are the basis for sensing and imaging methods based on coherent light scattering. Rather than being measured directly, underlying optical field autocorrelations (OFA) are typically inferred from intensity autocorrelations (IA). We show that direct measurements of OFAs using interferometric near-infrared spectroscopy (iNIRS) provide multiple advantages. Besides improving precision and accuracy of measurements, iNIRS also separates the OFA into static and dynamic components. We use this approach to non-invasively quantify dynamics in the nude mouse brain in vivo, avoiding contamination from non-ergodic scattering processes in the skull and superficial layers.
