AI-enhanced Metalens achieves high-resolution and full-color …
2 days ago · The outer regions of the metalens images (yellow box) are successfully restored, even though those are more severely degraded than the inner region (red box) due to the angular aberration under high viewing angle. “We propose a comprehensive imaging solution poised to replace conventional geometric lens-based systems.
Metalenses harness AI for superior performance - SPIE
4 days ago · The metalens itself is fabricated using nanoimprint lithography, a scalable and cost-effective method, followed by atomic layer deposition, allowing for large-scale production of these lenses. The metalens is designed to focus light efficiently but, like most metalenses, suffers from chromatic aberration and other distortions due to its ...
Are cameras about to get even smaller? A new 100mm metalens …
6 days ago · Metalenses are tiny optical elements that can manipulate electromagnetic waves, or light, just like traditional lenses, but are thinner than a sheet of paper. This new technology could dramatically change the size of imaging devices, making cameras smaller and smartphones less bulky. The concept of metamaterials has been around for a while.
New lens could help doctors see deeper inside the body than ever …
1 day ago · This metalens could make endoscopes much smaller and more flexible, allowing doctors to reach areas inside the body that were previously inaccessible. This new lens system could shrink the size of ...
New lens system for endoscopes could allow physicians to see …
6 days ago · This new metalens system uses quantitative phase imaging — a microscopy technique that measures the phase of light as it passes through a transparent or semi-transparent sample — and depth sensing to render a three dimensional, full-color video in real time with very little computing needed. It also is tiny, with an aperture width of 0.5 ...
New lens system for endoscopes could allow physicians to see …
5 days ago · A coin-shaped metalens at the front end of the endoscope directs three cones of red, green, and blue light to a rainbow of focal spots that probe the three-dimensional target (spoked wheel at right).
Compound metalens achieves distortion-free im | EurekAlert!
5 days ago · Researchers have developed a compound metalens that enables distortion-free imaging with a wide field of view, as presented in a study published in Engineering.
Computational metaoptics for imaging - arXiv.org
5 days ago · This challenge can be overcome by combining a single-layer polarization- and spatially-multiplexed metalens with a polarization camera to simultaneously record four polarization shearing interference patterns along both in-plane directions, thus allowing the deterministic reconstruction of the complex amplitude light field in a single shot ...
Deep-learning-driven end-to-end metalens imaging - Nweon Paper
1 day ago · A deep-learning-based image restoration framework is proposed to overcome these limitations and realize end-to-end metalens imaging, thereby achieving aberration-free full-color imaging for mass-produced metalenses with 10 mm diameter. Neural-network-assisted metalens imaging achieved a high resolution comparable to that of the ground truth image.
10 Reasons to Wait for Next Year's iPhone 17 - MacRumors
3 days ago · 9. Smaller Dynamic Island. iPhone 17 Pro Max. Apple's highest-end 2025 iPhone will feature a significantly narrower Dynamic Island, thanks to the device's adoption of a smaller "metalens" for the ...
