This work analytically examines some dependences of the differential pathlength factor
(DPF) for steady-state photon diffusion in a homogeneous medium on the shape, dimension …

We investigate the optical properties of the brain in 23 neonates in vivo using a frequency
domain near-infrared spectroscopy (NIRS). In this study, a calibration procedure is …

Frequency domain near-infrared spectroscopy (FD-NIRS) is a non-invasive method for
measuring optical absorption in the brain. Common data analysis procedures for FD-NIRS …

Near-infrared (NIR) optical properties of turbid media, eg, tissue, can be accurately
quantified noninvasively using methods based on diffuse reflectance or transmittance, such …

The near infrared spectroscopy (NIRS) frequency-domain multi-distance (FD-MD) method
allows for the estimation of optical properties in biological tissue using the phase and …

The goal of frequency-domain optical absorption spectroscopy is the noninvasive
