A new metasurface design lets light of different spins bend, focus, and behave independently—while staying sharp across many ...

High-accuracy determination of the position of features in the field of view (positioning) is one of the most significant functions of a camera used on a satellite. Knowledge of the inner orientation ...

Geometrical optics, a branch of optics that eschews wave phenomena in favour of ray propagation, continues to underpin advances in lens design and optical engineering. Contemporary studies in this ...

Researchers developed a nonlinear nonlocal metasurface that converts infrared light to visible and steers it by combining ...

Polarized light is one of the most powerful tools scientists have for peering inside matter, yet the way it twists, scatters and transforms inside real-world materials has long been treated as a black ...
