That's because the structure of a cat's eye has a tapetum lucidum, a mirror-like layer immediately behind the retina. Light entering the eye that is not focused by the lens onto the retina is reflected off the tapetum lucidum, where the retina gets another chance to receive the light, process it, and send impulses to the optic nerve. /news/2024-03-team-acoustic-crystal-smooth-elastic.html Optics & Photonics Sat, 23 Mar 2024 07:30:01 EDT news630322112 Researcher discovers how to predict movement for animals of all shapes, sizes and speeds A West Virginia University mechanical engineer has developed a way to predict the neuron and muscle patterns controlling locomotion for animals of any size, moving at any speed. /news/2024-01-movement-animals-sizes.html Biotechnology Molecular & Computational biology Wed, 31 Jan 2024 09:13:21 EST news625914796 A magnetically actuated acoustic metamaterial Space coiling acoustic metamaterials are static and require manual reconfiguration for sound-field modulation.

Most well-established optical metasurfaces are, however, static and feature well-defined optical responses that are determined by optical metasurface configurations set during their development. The dynamic configurations of the materials investigated so far often show specific limitations and reduced reconfigurability.

Using the setup, they developed an electrically driven, dynamic microelectromechanical system-optical metasurface platform to regulate phases alongside amplitude modulations of the reflected light by finely actuating the MEMS mirror. Using this platform, they showed how the components afforded polarization-independent beam steering and two-dimensional focusing with high modulation efficiencies and fast responses. The platform offers flexible solutions to realize complex dynamics of 2D wavefront regulations with applications in reconfigurable and adaptive optical networks and systems. /news/2021-07-piezoelectric-microelectromechanical-system-based-optical-metasurfaces.html Optics & Photonics Mon, 05 Jul 2021 08:00:01 EDT news544689983
