Inverse problem of Mueller polarimetry for metrological applications
Journal of Inverse and Ill-Posed Problems, 2021Abstract Inverse problem of Mueller polarimetry is defined as a determination of geometrical features of the metrological structures (i.e. 1D diffraction gratings) from its experimental Mueller polarimetric signature. This nonlinear problem was considered as an optimization problem in a multi-parametric space using the least square ...

Model for the depolarizing retarder in Mueller matrix polarimetry
Journal of the Optical Society of America A, 2022We advance an analytical model describing the polarimetric response of a depolarizing retarder whose retardance varies spatially in magnitude or in orientation. The variation of the retarder parameters may be either of deterministic or of random nature. The model provides both the mean values and the uncertainties of the parameters.

Mueller polarimetry for the detection of cancers
SPIE Proceedings, 2014Polarization measurements allow one to enhance imaging contrast of superficial tissues and obtain new polarization sensitive parameters for better description of the micro- and macro- structural and optical properties of complex tissues. Since the majority of cancers originate in the epithelial layer, probing the morphological and pathological changes ...

Determination of Mueller Matrix for Metal Substrates by Stokes Polarimetry
IEEE Transactions on Instrumentation and Measurement, 2021This article focuses on a polarization measurement method based on Mueller calculus for determining the polarization properties of metal substrates. As the Mueller matrix of a medium provides all its polarization-altering properties, the presented method enables to predict the effect of any optically absorbing media on the polarization state of light ...

Characterization of cervical tissue using Mueller matrix polarimetry
Lasers in Medical Science, 2023The cervix is composed of layers of squamous epithelium and connective tissue. The main component of the cervical connective tissue is collagen, which has specific orientations in different parts of the cervix and provides mechanical strength. Cervical pathologies such as cervical intraepithelial neoplasia (CIN), cancer, pregnancy, and spontaneous ...

Mueller and Kennaugh matrices in radar polarimetry
IEEE Transactions on Geoscience and Remote Sensing, 1994This paper is concerned with the notions of the Mueller matrix and the Kennaugh (or Stokes scattering) matrix, that are commonly used in the field of radar polarimetry. Although these two matrices are quite similar, there exists a basic difference between them that seems to have been overlooked by a number of researchers, resulting in a great deal of ...

Mueller polarimetry in the back focal plane
SPIE Proceedings, 2007A new Mueller polarimeter based on liquid crystals and a microscope objective is presented, for the characterization of diffraction gratings in a conical diffraction mounting. Fast measurements of complete Mueller matrices over a range of polar angles (0-56°) and azimuthal angles (0-360°) are achieved without mechanical movements.
