Diattenuation Imaging reveals different brain tissue properties [PDF]

open access: yesScientific Reports, 2019
AbstractWhen transmitting polarised light through histological brain sections, different types of diattenuation (polarisation-dependent attenuation of light) can be observed: In some brain regions, the light is minimally attenuated when it is polarised parallel to the nerve fibres (referred to as D+), in others, it is maximally attenuated (referred to ...

Single shot diattenuation imaging by circular polarization orthogonality breaking

Proceedings of SPIE, 2015
A novel technique is proposed to unambiguously determine the magnitude and orientation of linear dichroism. It relies on the use of a dual-frequency dual-polarization coherent source emitting two orthogonal circularly polarized modes at the output.

Infrared linear diattenuation and birefringence spectra of ferroelectric liquid crystals

Optics Letters, 1992
Linear diattenuation and linear birefringence spectra of three ferroelectric liquid-crystalline materials, 764E, SCE4, and SCE9, are presented for the wavelength region from 2.5 to 12 microm. Relatively high birefringence (Deltan >/= 0.1) was found in the transmission bands from 2.5 to 3.2 microm and 3.6 to 5.7 microm, with only a small amount of ...

Diattenuation and polarization preservation of retinal nerve fiber layer reflectance

Applied Optics, 2003
The diattenuation spectrum of the retinal nerve fiber layer (RNFL) reflectance has been predicted to depend strongly on the relative refractive index (m) of light-scattering cylinders. To constrain the values of m, diattenuation of the RNFL reflectance of isolated rat retina was measured with a multispectral imaging micropolarimeter.
