Using polarimeter and Stokes parameters for measuring linear birefringence and diattenuation properties of optical samples [PDF]

EPJ Web of Conferences, 2010
A technique is proposed for measuring the linear birefringence and linear diattenuation of an optical sample using a polarimeter. In the proposed approach, the principal axis angle (α), phase retardance (β), diattenuation axis angle (θd), and ...

Concept Design of a Multiwavelength Aerosol Lidar System With Mitigated Diattenuation Effects and Depolarization-Measurement Capability [PDF]

EPJ Web of Conferences, 2016
It is known that the retrieval of aerosol extinction and backscatter coefficients from lidar data acquired through so-called total-power channels – intended to measure the backscattered power irrespective of the polarization – can be adversely affected ...

Linear diattenuation imaging of biological tissues with near infrared Mueller scanning microscopy

Biomedical Optics Express, 2020
Among the multitude of optical polarization contrasts that can be observed in complex biological specimens, linear diattenuation (LD) imaging has received little attention. It is indeed challenging to image LD with basic polarizing microscopes because it is often relatively small in comparison with linear retardance (LR). In addition, interpretation of

Polarimetric Detection of Chemotherapy-Induced Cancer Cell Death

Applied Sciences, 2019
Imaging polarimetry is a focus of increasing interest in diagnostic medicine because of its non-destructive nature and its potential to distinguish normal from tumor tissue. However, handling and understanding polarimetric images is not an easy task, and

Development of a linear diattenuation sensitive semi-autonomous and portable digital lensless holographic microscope [PDF]

, 2023
This document presents the development of a linear diattenuation sensitive, semi-autonomous and portable digital lensless holographic microscope (DLHM). With the development of this project, we aim to improve the performance of this microscopy technique and to broaden the possibilities for a portable DLHM device.

Harvesting the Spin-Orbit Interaction of Light to Generate Helicity-Dependent Complex Rotational Motion in Optically Trapped Mesoscopic Matter. [PDF]

Nanophotonics
Spin–orbit interaction (SOI) of light is exploited to generate helicity‐dependent complex rotational and revolution dynamics in optical tweezers. At the trap center, particle rotation is governed by the direct helicity that follows the input polarization.

Extended Representation of Mueller Matrices

Photonics, 2023
The so-called arbitrary decomposition of a given Mueller matrix into a convex sum of nondepolarizing constituents provides a general framework for parallel decompositions of polarimetric interactions.
