En el presente trabajo presentamos un análisis de la propagación de la luz en medios fuertemente dispersivos y de baja capacidad de absorción, denominados medios turbios, compuestos por capas de características ópticas bien de nidas, haciendo us

In the present contribution we investigate the images of CW diffusely reflected light for a point-like source, registered by a CCD camera imaging a turbid medium containing an absorbing lesion. We show that detection of μa variations (absorption ano

One possible application of Near Infrared techniques is to analyze human brain metabolic activity. Currently used models take into account the layered structure of the human head but, usually, they do not consider the non-planar surface of some of th

Simultaneous retrieval of optical and geometrical parameters of multilayered turbid media via state-estimation algorithms

In the present paper we propose an implementation of the Kalman filter algorithm, which allows simultaneous recovery of the absorption coefficient, the reduced scattering coefficient and the thicknesses of multi-layered turbid media, with the deepest

Retrieval of the optical properties of a semiinfinite compartment in a layered scattering medium by single-distance, time-resolved diffuse reflectance measurements

Autor: J. A. Pomarico, D. I. Iriarte, Dirk Grosenick, Héctor Alfredo García, Rainer Macdonald

Functional analysis of the human brain requires methods that take the layered structure of the head into account. In this work we introduce an improved theoretical model that describes light propagation in multilayered, turbid cylinders with a infini

Diffuse light transmission profiles obtained using CW: A comparative analysis with time resolved experiments

Autor: J. A. Pomarico, N A Carbone, H. O. Di Rocco, M. V. Waks Serra, Héctor Alfredo García, H. Ranea-Sandoval, D. I. Iriarte

In this work, we investigate the CW transmitted light profiles when an inhomogeneity is immersed in highly scattering media slabs. These profiles show an interesting effect whenever the absorption coefficient, μa, of the inclusion happens to be high
