Method for broadband spectroscopy of light transport through opaque scattering media
Muskens, O.L. and Lagendijk, A. (2009) Method for broadband spectroscopy of light transport through opaque scattering media. Optics Letters, 34, (4), 395-397. (doi:10.1364/OL.34.000395).
We present a new broadband technique for the measurement of di®use light transport through
opaque scattering media. Using the spectral correlations introduced by a scattering medium onto
a white-light supercontinuum spectrum, the di®usion constant of light is determined over a wide
spectral range in the visible and near infrared. Independent broadband measurements of both the
transport mean free path and the di®usion constant are used to calculate the spectral dependence
of the energy velocity in a porous GaP slab. Broadband correlation spectroscopy is found to be an
excellent tool for the characterization of random scattering media.
