We investigated birefringence-derived artifacts that potentially mimic focal defects of the lamina cribrosa (focal LC defects) in optical coherence tomography (OCT) imaging of eyes with glaucoma. This ...

Bio-based plastics from renewable resources are considered eco-friendly. It is hoped they will contribute to a more sustainable society and help prevent global warming. Besides cellulose, which is the ...

ETH researchers led by Raffaele Mezzenga have developed a new diagnostic method. It is based on Birefringence, the ability of substances to change the polarization state of light. With this method, ...

Mid- and far-infrared birefringent crystals are key functional materials for polarization control, laser technologies, and infrared photonics. However, existing materials generally suffer from limited ...

Until recently, techniques for measuring birefringence have hardly altered with observations being made using standard polarising microscopes with white light and crossed polars, which can lead to ...

Researchers find gravitational lensing has significant effect on cosmic birefringence. ScienceDaily. Retrieved May 29, 2026 from www.sciencedaily.com / releases / 2023 / 11 / 231102135148.htm Kavli ...

This diagram represents the the light of a neutron star passing through an area of space where vacuum birefringence, a theory of quantum electrodynamics, is occurring. The light\'s magnetic and ...

Multiple independent analyses of the oldest light in the universe now point to a subtle but persistent twist in its polarization, a signal that, if confirmed, cannot be explained by the Standard Model ...

A new diagnostic method has been created, based on Birefringence, the ability of substances to change the polarization state of light. With this method, doctors around the world can easily, rapidly ...

With this method, doctors around the world can easily, rapidly and reliably detect malaria, Ebola or HIV to name only a few. Nothing could be simpler: a drop of blood is placed on a special carrier ...
