Spin‐Orbit Photonics with Potato Starch Lenses

open access: yesAdvanced Optical Materials, Volume 13, Issue 21, July 25, 2025.
Native potato starch spherulites are introduced as volumetric optical elements that modulate both dynamic and geometric phases of light. These spherulites focus light and generate optical vortices via spin‐orbit interaction, functioning as polarization‐sensitive microlenses. Their unique radial anisotropy enables applications in vortex beam generation,

End-to-end nanophotonic inverse design for imaging and polarimetry

open access: yesNanophotonics, 2020
By codesigning a metaoptical front end in conjunction with an image-processing back end, we demonstrate noise sensitivity and compactness substantially superior to either an optics-only or a computation-only approach, illustrated by two examples ...

Scattering Mechanism Extraction by a Modified Cloude-Pottier Decomposition for Dual Polarization SAR

open access: yesRemote Sensing, 2015
Dual polarization is a typical operational mode of polarimetric synthetic aperture radar (SAR). However, few studies have considered the scattering mechanism extraction of dual-polarization SARs.

Going Beyond Standard Ocean Color Observations: Lidar and Polarimetry

open access: yesFrontiers in Marine Science, 2019
Passive ocean color images have provided a sustained synoptic view of the distribution of ocean optical properties and color and biogeochemical parameters for the past 20-plus years. These images have revolutionized our view of the ocean.

Asteroid Polarimetry

open access: yes, 2015
The application of the polarimetric technique to asteroid studies progressed significantly during the last decade. The most interesting results were the discovery of asteroids with peculiar polarimetric properties, new findings on wavelength dependence of polarization, and some improvements in the polarimetric method of albedo determination.

An Icon-Based Synoptic Visualization of Fully Polarimetric Radar Data

open access: yesRemote Sensing, 2012
The visualization of fully polarimetric radar data is hindered by traditional remote sensing methodologies for displaying data due to the large number of parameters per pixel in such data, and the non-scalar nature of variables such as phase difference ...
