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 ...
A new publication from Opto-Electronic Advances; DOI 10.29026/oea.2026.250149, discusses a quarter-wave geometric-phase route ...
Researchers developed a nonlinear nonlocal metasurface that converts infrared light to visible and steers it by combining ...
