Query: Brillouin imaging in turbid samples: the removal of multiple scattering
  contribution   We provide a new analytic expression and an innovative experimental method to
isolate the effect of multiple scattering (MS) in Brillouin investigation of
highly turbid media. On the one hand, an analytic model is given to describe
the spectrum in case of ill-defined exchanged wave-vector. On the other hand, a
new experimental method, named Polarization Gated Brillouin Spectroscopy
(PG-BS), is proposed for selecting the MS contribution through light
polarization. Both experimental and analytic methods are tested against a
benchmark material, milk, demonstrating their capability to extract reliable
micro-mechanical parameters even in highly turbid materials till now
inaccessible to in-depth Brillouin scattering investigation.
