چکیده
We present experimental depth-resolved complete polarization-sensitive measurements of a stack of linear retarders and glass plates by using what is to the best of our knowledge the first combination of a confocal imaging system with a complete Mueller matrix polarimeter. The axially resolved Mueller matrices were compared with a forward simulation, with good agreement.

Confocal scanning laser ophthalmoscopy improvement by use of Mueller-matrix polarimetry.
A new technique for improving the signal-to-noise ratio and the contrast in images recorded with a confocal scanning laser system is presented. The method is based on the incorporation of a polarimeter into the setup. After the spatially resolved Mueller matrix of a sample was calculated, images for incident light with different states of polarization were reconstructed, and both the best and t...
متن کاملMeasurement of parameters of polarization in the living human eye using imaging polarimetry
An imaging polarimeter using liquid-crystal variable retarders (Bueno, J. M., Artal, P. (1999). Double-pass imaging polarimetry in the human eye. Optics Letters, 24, 64-66) has been used to study the parameters of polarization in the living human eye. Retardation introduced by birefringent structures of the eye has been calculated by using a spatially resolved collection of Mueller matrices obt...

The Mueller matrix polarimetry is a useful technique for characterization and imaging of biological materials and turbid medium. The recoded transmitted Mueller matrix elements are highly intensity and wavelength dependent. We derived the sixteen Mueller matrix images out of forty-nine polarization configurations for characterization of the polystyrene sphere of 0.2 to 20 μm illuminated with po...
متن کاملTime-resolved switching analysis of a ferroelectric liquid crystal by snapshot Mueller matrix polarimetry.
An experimental snapshot Mueller matrix polarimeter based on wavelength polarization coding is used to get a time-resolved description of electric-field-induced fast transition within a ferroelectric liquid-crystal cell. The parameters extracted from experimental Mueller matrices are linked to the molecule director distribution to further determine the average trajectory and the collective beha...
متن کاملSnapshot retinal imaging Mueller matrix polarimeter
Early diagnosis of glaucoma, which is a leading cause for visual impairment, is critical for successful treatment. It has been shown that Imaging polarimetry has advantages in early detection of structural changes in the retina. Here, we theoretically and experimentally present a snapshot Mueller Matrix Polarimeter fundus camera, which has the potential to record the polarization-altering chara...
