Improved solutions of the diffusion equation for time-resolved and steady-state spatially
resolved reflectance are investigated for the determination of the optical coefficients of semi …

Tissue glucose levels affect the refractive index of the extracellular fluid. The difference in
refractive index between the extracellular fluid and the cellular components plays a role in …

We have designed a multisource frequency-domain spectrometer for the optical study of
biological tissues. Eight multiplexed, intensity-modulated LEDs are employed as the light …

A technique for measuring broadband near-infrared absorption spectra of turbid media that
uses a combination of frequency-domain (FD) and steady-state (SS) reflectance methods is …

We have used continuous-wave (CW) and frequency-domain spectroscopy to investigate
the optical properties of the newborn piglet brain in vivo and non-invasively. Three …

A multiwavelength, high bandwidth (1 GHz) frequency–domain photon migration (FDPM)
instrument has been developed for quantitative, non–invasive measurements of tissue …

We have studied light migration in highly scattering media theoretically and experimentally,
using the diffusion approximation in a semi-infinite-geometry boundary condition. Both the …

A theoretical approach is presented to determine absorption changes in different
compartments of a layered structure from distributions of times of flight of photons. In addition …

Near-infrared neuromonitoring (NIN) is based on near-infrared spectroscopy (NIRS)
measurements performed through the intact scalp and skull. Despite the important effects of …

A 1-GHz multifrequency, multiwavelength frequency-domain photon migration instrument is
used to measure quantitatively the optical absorption (μ_a) and effective optical scattering …
