This thesis presents a unique application of optical spectroscopy for a critical surgical need
in endocrine surgery today. Of the numerous optical techniques, fluorescence spectroscopy …

An exact solution of the time dependent diffusion equation for a layered diffusive medium
has been obtained by using a method based on the decomposition of the fluence rate in a …

The research presented in this thesis deals fundamentally with the interaction of light with
highly diffusive or scattering media. A particularly interesting example of such diffusive …

In this paper, a Monte Carlo based model of diffuse reflectance is introduced to retrieve the
light absorption and scattering coefficients of multi-layered tissue. The model consists of a …

When a pulse of light enters a diffusive medium such as tissue, it undergoes a number of
changes. Most obviously, its intensity is attenuated due to the scattering and absorption …

The current intra-operative method for identifying parathyroid glands involves a systematic
exploration of the neck in which the surgeon is primarily relying on visual distinction to …

In this work, we explore diffuse correlation spectroscopy (DCS) in a two-layered geometry.
We compare the effiency of an homogeneous and a two-layered model to recover flow …

The diffusion approximation is useful for many optical diagnostics modalities, such as near-
infrared spectroscopy. However, the simple normal incidence, semi-infinite layer model may …

When a near infrared (NIR) light shines on a biological tissue, a very small quantity of the
photons in the light, called ballistic or snake photons, travel in a nearly straight path along …

Tissue-like phantom experiments were performed in order to investigate the possibility of
using the polarized light scattering spectroscopy for skin cancer diagnosis. Using a two-layer …
