Principle and Implementation of Stokes Vector Polarization Imaging Technology

open access: yesApplied Sciences, 2022
Compared with traditional imaging methods, polarization imaging has its unique advantages in many directions and has great development prospects. It is one of the hot spots of research and development at home and abroad. Based on the polarization imaging

Demonstration of amplitude-distortion correction by modal dispersal and phase conjugation [PDF]

open access: yes, 1987
We demonstrate experimentally and explain theoretically polarization-preserving imaging through a lossy amplitude-distorting medium. This is accomplished by propagating the beam, before its arrival at the lossy distorting medium, through a (multi) mode ...

Polarization-resolved second-harmonic-generation optical coherence tomography in collagen [PDF]

open access: yes, 2004
We describe a novel imaging technique, second-harmonic-generation optical coherence tomography (SHOCT). This technique combines the spatial resolution and depth penetration of optical coherence tomography (OCT) with the molecular sensitivity of second ...

A Table of Some Coherency Matrices, Coherency Matrix Factors, and Their Respective Mueller Matrices

open access: yesPhotonics, 2022
Many books on polarization give tables of Mueller matrices. The coherency matrix has been found useful for interpretetion of the Mueller matrix. Here we give a table of Mueller matrices M, coherency matrices C, and coherency matrix factors F for ...

Stereographical visualization of a polarization state using weak measurements with an optical-vortex beam [PDF]

open access: yes, 2014
We propose a stereographical-visualization scheme for a polarization state by two-dimensional imaging of a weak value with a single setup. The key idea is to employ Laguerre-Gaussian modes or an optical vortex beam for a probe state in weak measurement ...

The Magnetic Field Geometry in DR21 [PDF]

open access: yes, 2003
We present broadband imaging polarimetry of DR21 at 2.2$\mu$m. Background stars shining through the lobes of the bipolar outflow show polarization aligned with the long axis of the outflow, indicating a magnetic field geometry oriented along the flow ...

POLARIZATION IMAGING AND SCATTERING MODEL OF CANCEROUS LIVER TISSUES [PDF]

open access: yesJournal of Innovative Optical Health Sciences, 2013
We apply different polarization imaging techniques for cancerous liver tissues, and compare the relative contrasts for difference polarization imaging (DPI), degree of polarization imaging (DOPI) and rotating linear polarization imaging (RLPI ...

Rapid Detection of Camouflaged Artificial Target Based on Polarization Imaging and Deep Learning

open access: yesIEEE Photonics Journal, 2021
Polarization imaging has the advantage of detecting artificial targets based on their intrinsic characteristics. However, with the development of camouflage materials and camouflage shielding performance, the anti-optical detection technology for ...

Influence of absorption in linear polarization imaging of melanoma tissues [PDF]

open access: yesJournal of Innovative Optical Health Sciences, 2014
The contrast mechanism of different polarization imaging techniques for melanoma in mouse skin is studied using both experiments and Monte Carlo simulations.

Alkaline earth atoms in optical tweezers [PDF]

open access: yes, 2018
We demonstrate single-shot imaging and narrow-line cooling of individual alkaline earth atoms in optical tweezers; specifically, strontium-88 atoms trapped in $515.2~\text{nm}$ light.
