Urban objects classification using Mueller matrix polarimetry and machine learning
Optics Express, 2022 Detecting and recognizing different kinds of urban objects is an important problem, in particular, in autonomous driving. In this context, we studied the potential of Mueller matrix polarimetry for classifying a set of relevant real-world objects: vehicles, pedestrians, traffic signs, pavements, vegetation and tree trunks.

Mueller coherency matrix method for contrast image in tissue polarimetry [PDF]
SPIE Proceedings, 2007 In this work, we propose the use of the Mueller Coherency matrix of biological tissues in order to increase the information from tissue images and so their contrast. This method involves different Mueller Coherency matrix based parameters, like the eigenvalues analysis, the entropy factor calculation, polarization components crosstalks, linear and ...

Mueller matrix polarimetry of bianisotropic materials [Invited]
Journal of the Optical Society of America B, 2019 Mueller matrix polarimetry is a powerful optical technique for characterization of both anisotropic and bianisotropic materials. This review emphasizes methods for the interpretation of measured Mueller matrices, from the meanings of matrix symmetries, to ab initio calculations of Mueller matrices that begin with Maxwell’s equations operating on ...

Preservation of Historically and Scientifically Important Geospatial Data From Venus
Earth and Space Science, Volume 13, Issue 3, March 2026.Abstract A large volume of scientifically and historically important data from the early exploration of Venus is not widely available to researchers. Our work is focused on ameliorating this problem with the archival of geospatial data including radar, topography, and radiometry.

Laser &Photonics Reviews, Volume 20, Issue 4, 19 February 2026.Turbid media containing small‐sized Rayleigh‐regime scatterers present a ‘special case’ in which linearly polarized light is found to be less depolarized than circularly polarized light. The underlying mechanisms that give rise to this phenomenon are not yet understood.

Demonstration of Compact In situ Mueller-Matrix Polarimetry Based on Binary Polarization Rotators
IEEE Access, 2019 We develop a compact in situ Mueller-matrix polarimetry (MMP) based on binary polarization rotators for on-machine optical processing measurements. The presented in situ MMP could measure the polarization properties of free-space reflective samples by ...
