Polarimetric discriminators for SAR images
IEEE Transactions on Geoscience and Remote Sensing, 1992A method is developed for optimizing the degree of polarization of a partially polarized wave reflected by a nonstationary scattering object. The method permits, for a scattered wave and a given target characterized by its Mueller matrix, analytic computation of the maximum and minimum values of the degree of polarization, and the corresponding ...

Visible-regime polarimetric imager: a fully polarimetric, real-time imaging system
Applied Optics, 2003A fully polarimetric optical camera system has been constructed to obtain polarimetric information simultaneously from four synchronized charge-coupled device imagers at video frame rates of 60 Hz and a resolution of 640 x 480 pixels. The imagers view the same scene along the same optical axis by means of a four-way beam-splitting prism similar to ones

Polarimetric SAR imaging of buried landmines
IEEE Transactions on Geoscience and Remote Sensing, 1998If the fields incident on a buried body of revolution are polarized vertically or horizontally (relative to the ground), the backscattered fields are exclusively copolarized (i.e., there are no cross-polarized backscattered fields). After substantiating this theoretically, measured ultrawideband (UWB) synthetic aperture radar (SAR) data are used for ...

Polarimetric optical imaging of scattering surfaces
Applied Optics, 1996A polarimetric optical specular event detector (OSED) has been developed to provide spatially and temporally resolved polarimetric data of backscattering in the visible from water wave surfaces. The OSED acquires simultaneous, two-dimensionally resolved images of the remote target in two orthogonal planes of polarization.

Hierarchical segmentation of polarimetric SAR images
IEEE International Geoscience and Remote Sensing Symposium, 2003A hierarchical stepwise optimization process is used for polarimetric SAR image segmentation. The process starts with small sets of pixels as segments and then sequentially merges the segment pair that minimises a stepwise criterion. The polarimetric information could be represented by a covariance matrix.

Using polarimetric imaging for material classification
Proceedings 2003 International Conference on Image Processing (Cat. No.03CH37429), 2004In this paper we are mainly interested in the classification of images into different clusters, each corresponding to an object material in the imaged scene. For that purpose, the use of a polarimetric-based imaging system is proposed. This system has been developed in order to enlighten the huge potential of the information contained in polarization ...

Polarimetric BISAR Image Simulation and Analysis
IGARSS 2008 - 2008 IEEE International Geoscience and Remote Sensing Symposium, 2008Employing three-dimensional mapping and projection algorithm (MPA), imaging simulation of bistatic SAR (BISAR) observation over complex scenario is developed. Based on the explicit expression of point target response of stripmap BISAR imaging, raw data is efficiently generated from the scattering map pre-calculated by MPA.

Use of polarimetric imaging of emissive objects
SPIE Proceedings, 2017This paper describes the use of polarization information to estimate the shape of emissive objects in the field of nonconventional imaging techniques for 3D digitization. Using “Shape from Polarization” method which is applied in the far infrared for transparent object and in the near infrared for the molten metal.
