Fourier ptychography microscopy for digital pathology

Journal of Microscopy, Volume 300, Issue 2, Page 260-285, November 2025.
Abstract Fourier ptychography microscopy (FPM) has made significant progress since its invention in 2013, thanks to its adaptable nature, high resolution, and vast field‐of‐view capabilities. FPM is used in various medical applications across multiple optical wavelengths, from automated digital pathology to radiology and ultraviolet label‐free imaging.

High Precision Stokes Polarimetry for Scattering Light using Wide Dynamic Range Intensity Detector

MATEC Web of Conferences, 2015
This paper proposes a Stokes polarimetry for scattering light from a sample surface. To achieve a high accuracy measurement two approaches of an intensity detector and analysis algorism of a Stokes parameter were proposed.

Enhanced Circularly Polarized Lasing in Nanocellulose‐Silica Composites

Advanced Optical Materials, Volume 13, Issue 17, June 17, 2025.
This study demonstrates enhanced circularly polarized lasing emission using cholesteric crystalline nanocellulose (CNC) films embedded with silica nanospheres. The addition of silica spheres significantly boosts circular dichroism by suppressing linear diattenuation, improving the circular polarization.

Interplay of Circularly Polarized Light with Molecular and Structural Chirality: Chiral Lanthanide Complexes and Cellulose Nanocrystals

Advanced Optical Materials, Volume 12, Issue 34, December 3, 2024.
The interplay between the highly polarized luminesce of Eu chiral complexes, and the polarization selective reflection of the chiral nematic structures provided by cellulose nanocrystal (CNC) films is shown in this contribution. Abstract The interaction of circularly polarized (CP) light with chiral matter at different scales opens several ...

Nonlocality Enhanced Precision in Quantum Polarimetry via Entangled Photons

Advanced Quantum Technologies, Volume 7, Issue 11, November 2024.
A quantum polarimetry method using entangled photons to improve measurement precision is introduced. By calculating precision bounds and estimating the rotation angle of optical elements, both theoretically and experimentally, it is shown that the capability of entanglement to enhance accuracy is diminished with noise.
