Total retardance measurements based on the complex Fourier coefficients for the rotating polarizer analyzer system [PDF]

open access: yesHeliyon, 2023
We propose a demodulation algorithm based on the calculus of the complex Fourier coefficients; we used a dual rotating polarizer-analyzer polarimeter to show the feasibility of our proposal.

Conventions and formulas for using the mueller-stokes calculus in ellipsometry [PDF]

open access: bronzeSurface Science Letters, 1980
An analysis of the compatability of ellipsometry conventions with the Mueller-Stokes calculus has shown that, for the two approaches to be consistent, modifications to the 1968 Nebraska ellipsometry conventions are necessary. A sign convention is proposed which specifies the ellipticity angle and the fourth Stokes parameter to be positive when the tip ...

Reduction of polarimetric data using Mueller calculus applied to Nasmyth instruments [PDF]

open access: greenSPIE Proceedings, 2008
We present a method based on Mueller calculus to calibrate linear polarimetric observations. The key advantages of the proposed way of calibration are: (1) that it can be implemented in a data reduction pipeline, (2) that it is possible to do accurate polarimetry also for telescopes/instruments with polarimetric non-friendly architecture (e.g.

Robust overlay metrology with differential Mueller matrix calculus

open access: goldOptics Express, 2017
Overlay control is of vital importance to good device performances in semiconductor manufacturing. In this work, the differential Mueller matrix calculus is introduced to investigate the Mueller matrices of double-patterned gratings with overlay displacements, which helps to reveal six elementary optical properties hidden in the Mueller matrices.

Reveal linear optical effects of the liquid crystal by Stokes-Mueller calculus and θ-scan technology [PDF]

open access: green, 2022
Abstract Based on the Stokes-Mueller calculus, linear optical effects of liquid crystals were investigated using the θ-scan technology. Usually, when a circularly polarized light beam passes through an anisotropic optical medium, the transmitted light beam behaves as elliptically polarized light.

Generalized Jones & Mueller calculus for anisotropic media [PDF]

open access: gold
The interaction of non-paraxial polarized light with anisotropic media is inherently 3-D, and described by the calculus of generalized Jones & Mueller matrix (GJM & GMM). However, existing two calculus treat the interaction as the paraxial transformation with 3-D rotation, neglecting the vector property of the local light path.

Generalized Jones-Mueller calculus for optical anisotropic media

open access: goldOptics Express
3-D matrix calculus plays a critical role in describing 3-D polarized transformations. However, existing two 3-D calculi, generalized Jones and Mueller matrix calculus (GJM and GMM), remain flawed and incomplete. First, the global connection between two matrices has not been theoretically explored and established, which results in their independence ...

Dynamic instability of vibrations of thin-wall composite curvorine viscoelastic tubes under the influence of pulse pressure [PDF]

open access: yesE3S Web of Conferences, 2020
In this paper the results of a study of the dynamic characteristics of thin-walled composite curved viscoelastic pipes under the influence of internal pulsating pressures is presented. The relationship between stress and strain is described by the Aviary
