Parallel Phase-Shifting Digital Holographic Phase Imaging of Micro-Optical Elements with a Polarization Camera

open access: yesPhotonics, 2023
In this paper, we propose a measurement method of micro-optical elements with parallel phase-shifting digital holographic phase imaging. This method can record four phase-shifting holograms with a phase difference of π/2 in a single shot and correct the ...

Effective spectral optical functions of lamellar nanogratings [PDF]

open access: yesJournal of the European Optical Society-Rapid Publications, 2006
Spectral properties of lamellar sub-wavelength gratings (nanogratings) are described by effective medium approximation (EMA). Analytical spectral formulae for ordinary and extraordinary effective optical functions are derived for nanogratings consisting ...

Monolithically-stacked thin-film solid-state batteries

open access: yesCommunications Chemistry, 2023
The power capability of Li-ion batteries has become increasingly limiting for the electrification of transport on land and in the air. The specific power of Li-ion batteries is restricted to a few thousand W kg−1 due to the required cathode thickness of ...

Triple-product asymmetry in the radiative two-pion tau decay

open access: yesJournal of High Energy Physics, 2022
In this work, we perform a detailed study of the τ − → π − π 0 γν decay process within the resonance chiral theory. We pay special attention to the triple-product asymmetry in the τ − → π − π 0 γν process.

Probing viscoelastic properties of a thin polymer film sheared between a beads layer and quartz crystal resonator [PDF]

open access: yes, 2009
We report measurements of viscoelastic properties of thin polymer films of 10-100 nm at the MHz range. These thin films are confined between a quartz crystal resonator and a millimetric bead layer, producing an increase of both resonance frequency and ...

Effect of substrate temperature on structural and optical properties of cadmium sulfide thin films prepared by evaporation thermal deposition

open access: yesAl-Mustansiriyah Journal of Science, 2019
In this research , we study the effect of substrate temperature (423K and 473K) on structural and optical properties for thin films of cadmium sulfide (CdS) by evaporation thermal deposition method on glass substrates and the thickness was about (390nm ...
