Single-pixel polarimetric imaging [PDF]
Optics Letters, 2012 We present an optical system that performs Stokes polarimetric imaging with a single-pixel detector. This fact is possible by applying the theory of compressive sampling to the data acquired by a commercial polarimeter without spatial resolution. The measurement process is governed by a spatial light modulator, which sequentially generates a set of ...

Polarimetric calibration strategy for long-duration imaging with a ground-based SAR [PDF]
, 2005 The Ground-Based Synthetic Aperture Radar (GB-SAR) facility in the UK provides high-resolution, fully polarimetrically calibrated L- through X-band SAR imagery, principally of targets of remote sensing interest such as soils and vegetation.

Polarimetric imaging with high spatial resolution. [PDF]
Sci RepDespite its critical importance in many biomedical devices, the polarization of light is often neglected or considered as a problem to be contained. The reason is related to considerable challenges to measure it. In the present work, a simple motion-free method of detection of the polarization of light is developed based on a guest-host nematic liquid ...

Optics Express, 1999 Scenes from a Mueller matrix movie of a brass cone are shown. From the Mueller matrix image, a variety of polarization measures are calculated and displayed. These polarization images reveal considerable details about the geometry of the cone despite the fact that the images are taken from a single vantage point, i. e. they are "flat images".

Polarimetric images with the GMRT [PDF]
Proceedings of ISKAF2010 Science Meeting — PoS(ISKAF2010), 2010 We present the first set of polarimetric images made with the GMRT. These were obtained as part of the program to commission the polarization mode at the telescope. We find that the instrumental polarization leakage at the GMRT varies with frequency. It is hence necessary to solve for the leakage as a function of spectral channel.

Wavelet-Based Compressed Sensing for SAR Tomography of Forested Areas [PDF]
, 2012 Synthetic aperture radar (SAR) tomography is a 3-D imaging modality that is commonly tackled by spectral estimation techniques. Thus, the backscattered power along the cross-range direction can be readily obtained by computing the Fourier spectrum of a ...
