Hybrid Dual-Polarization Synthetic Aperture Radar

Remote Sensing, 2019
Compact polarimetry for a synthetic aperture radar (SAR) system is reviewed. Compact polarimetry (CP) is intended to provide useful polarimetric image classifications while avoiding the disadvantages of space-based quadrature-polarimetric (quad-pol) SARs.

Correction of Ionosphere for InSAR by the Combination of Differential TEC Estimators [PDF]

, 2013
Low frequency spaceborne SAR configurations are favoured for global forest mapping applications and D-InSAR applications over natural terrain. Several missions have been scheduled to be launched / or proposed to be implemented in the next years: JAXA’s ...

Characterization of Polarimetric Properties in Various Brain Tumor Types Using Wide-Field Imaging Mueller Polarimetry [PDF]

Neuro-oncological surgery is the primary brain cancer treatment, yet it faces challenges with gliomas due to their invasiveness and the need to preserve neurological function.

Underwater Imaging Based on LF and Polarization

IEEE Photonics Journal, 2019
The underwater image restoration based on polarization information has achieved good results in improving the image quality in scattering media. However, the previous methods are difficult to obtain the true distribution of degree of polarization in the ...

Polarimetric Imaging Using One Fractal SNSPD

, 2022
We demonstrate a polarimetric imaging system with one fractal superconducting nanowire single-photon detector and time-multiplexed photon-counting scheme, which allows us to obtain images with multiple types of contrast.

Polarimetric imaging and blood vessel quantification

Optics Express, 2004
We applied a polarimetric analysis to retinal imaging, to examine the potential improvement in characterizing blood vessels. To minimize the reflection artifact of the superficial wall of the blood vessel, we computed depolarized light images by removing the polarization retaining light reaching the instrument.

Polarimetric characterisation of two layered frozen lakes [PDF]

, 2011
In terms of radar remote sensing, one of the challenges of future planetary SAR missions will be the estimation of surface, subsurface and upper layer geometric and dielectric characteristics that translate to the localization of subsurface ice and water

First 3-D reconstructions of target hidden beneath foliage by means of polarimetric SAR tomography [PDF]

, 2012
SAR tomography (SARTom) is an imaging technique that allows multiple phase center separation in the vertical direction, leading to a 3-dimensional (3D) reconstruction of the imaged scene. Retrieval of volume structure information (e.g.

Reflection mode polarimetry guides laser mass spectrometry to diagnostically important regions of human breast cancer tissue

Scientific Reports
To enhance the clinical utility of mass spectrometry (MS), lengthy dwell times on less informative regions of patient specimens (e.g., adipose tissue in breast) must be minimized. Additionally, a promising variant of MS known as picosecond infrared laser
