Monte Carlo simulation of the field back-scattered from rough surfaces

Christian Depeursinge, Yves Delacrétaz, Stéphane Chamot

A novel approach for the simulation of the field back-scattered from a rough surface is presented. It takes into account polarization and multiple scattering events on the surface, as well as diffraction effects. The validity and usefulness of this simulat ...

Determination of local optical properties of the rat barrel cortex during neural activation: Monte-Carlo approach to light propagation

Pierre Magistretti, Christian Depeursinge, Pierre Marquet, Stéphane Chamot, Elena Migacheva

Spatially-spectrally-resolved reflectance measurements allow in vivo measuring the optical coefficients of absorption and scattering within the cortical tissue. This method, if applied to neural tissue during enhanced activity, could allow a straightforwar ...

Signification of the phase function parameter gamma explored with a fractal distribution of scatterers

Christian Depeursinge, Pierre Marquet, Stéphane Chamot, Elena Migacheva

The optical properties within limited volumes of diffusive media can be probed by carrying spatially-resolved measurements of diffused light at short source-detector separation (typically one scattering mean free path). At such distance, analytical models ...

MEMS for enhanced optical diagnosis in microscopy

Christian Depeursinge, Stéphane Chamot

Endoluminal microscopy and spectroscopy could significantly improve the efficiency of clinical endoscopic examination by allowing in-situ detection, staging and grading of potentially cancerous lesions. Indeed, high-end optical microscopy techniques such a ...
