Colorimetric discrimination for Stokes polarimetric imaging

Optics Express, 2017
Traditional methods of discrimination for Stokes polarimetric imaging use grayscale images, in which the difference of the polarimetric properties is only reflected by the difference of grayscale. In this paper, we propose a method of colorimetric discrimination and classification for Stokes polarimetric imaging by the composed color polarimetric image,

Spectrally Tunable 2D Material‐Based Infrared Photodetectors for Intelligent Optoelectronics

Advanced Functional Materials, Volume 36, Issue 27, 2 April 2026.
Intelligent optoelectronics through spectral engineering of 2D material‐based infrared photodetectors. Abstract The evolution of intelligent optoelectronic systems is driven by artificial intelligence (AI). However, their practical realization hinges on the ability to dynamically capture and process optical signals across a broad infrared (IR) spectrum.

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.

Near real-time polarimetric imaging system

Journal of Biomedical Optics, 2013
A new imaging technique which enables near real-time multispectral acquisition of the so-called degree of polarization (DOP) in polarimetry using incoherent white light is described. The experimental setup allows the interactive and dynamic acquisition of DOP for all the possible elliptic polarization states.

Polarization Changes in Lunar Simulant Soil: The Role of Incident, Reflection, and Off‐Plane Angles

Earth and Space Science, Volume 13, Issue 4, April 2026.
Abstract Observing the polarization of the lunar regolith is essential for obtaining detailed information about the composition and characteristics of lunar soil. Observations conducted via lunar orbiters facilitate polarization measurements over wide areas; however, achieving very high‐resolution imaging requires either a large optical system or a ...
