Abstract

An optical device intended for the analysis of a scattering medium, including at least one light source distant from the scattering medium and capable of providing an incident light beam intended to illuminate the scattering medium; at least one sensor capable of detecting a radiation emitted by the scattering medium; a support of the scattering medium at least partially non-absorbing for the incident light beam and the scattered radiation. All or part of the support is formed of a scattering material having a decreased scattering coefficient greater than 0.1 cm−1 and smaller than 700 cm−1.
