An unexpected discovery in a Harvard lab has led to a breakthrough insight into choosing an unconventional material, silica, ...

Abstract: The vortex polarization direction indicator (Vortex-PDI), comprising a half-wave vortex retarder and an analyzer, enables single-shot characterization of linearly polarized light. This study ...

Scientists at the University of Oxford demonstrate an approach to interpreting how materials interact with polarized light, which could help advance biomedical imaging and material design. Their work, ...

Photoplethysmography (PPG) is an optical sensing technique that measures blood volume changes and underpins devices ranging from hospital-grade pulse oximeters to consumer wearables that track heart ...

Abstract: Aiming at the polarized light transmission characteristics under complex sea fog environment, the sea fog is divided into two layers of salt fog layer and water fog layer. Firstly, the ...
