Transmission of classically entangled beams through mouse brain tissue.

Light transmission of Laguerre-Gaussian vector vortex beams in different local regions in mouse brain tissue is investigated. Transmittance is measured in the ballistic and diffusive regions with various polarizations states and orbital angular momentums (OAM). The transmission change observed with structured light other than linear polarization is attributed to chiroptical phenomena from the chiral brain media and the handedness of the light.
