Method for broadband spectroscopy of light transport through opaque scattering media

By O.L. Muskens and A. Lagendijk

Abstract

We present a new broadband technique for the measurement of di®use light transport through<br/>opaque scattering media. Using the spectral correlations introduced by a scattering medium onto<br/>a white-light supercontinuum spectrum, the di®usion constant of light is determined over a wide<br/>spectral range in the visible and near infrared. Independent broadband measurements of both the<br/>transport mean free path and the di®usion constant are used to calculate the spectral dependence<br/>of the energy velocity in a porous GaP slab. Broadband correlation spectroscopy is found to be an<br/>excellent tool for the characterization of random scattering media
