Neural network assisted high-spatial-resolution polarimetry with non-interleaved chiral metasurfaces
Light: Science & Applications, 2023 Polarimetry plays an indispensable role in modern optics. Nevertheless, the current strategies generally suffer from bulky system volume or spatial multiplexing scheme, resulting in limited performances when dealing with inhomogeneous polarizations. Here,

Experimental obtaining of polarization ghost images by ghost polarimetry [PDF]
EPJ Web of Conferences, 2019 The paper presents the experimental implementation of a new version of the ghost image method ghost polarimetry in unpolarized light. Like conventional polarimetry, ghost polarimetry is used to study the polarization properties of objects.

Mueller Matrix Microscopy for In Vivo Scar Tissue Diagnostics and Treatment Evaluation
Sensors, 2022 Scars usually do not show strong contrast under standard skin examination relying on dermoscopes. They usually develop after skin injury when the body repairs the damaged tissue.

Decoding THz-Driven Dynamic Fingerprints of Ferroelectric Nanotwin Networks. [PDF]
Adv MaterABSTRACT Ultrafast polarization dynamics in ferroelectrics are of considerable interest for high‐speed tunable dielectrics and electro‐optics. Extended domain wall networks formed in ferroelectric twin nanodomains can support collective dynamics in the terahertz regime but require techniques that track polarization and strain evolution driven by ...

Entangled photon polarimetry [PDF]
Optics Express, 2010 We construct an entangled photon polarimeter capable of monitoring a two-qubit quantum state in real time. Using this polarimeter, we record a nine frames-per-second video of a two-photon state's transition from separability to entanglement.
