Metalens uses AI to enable high-resolution, full-color imaging of compact optical systems
A metalens, consisting of an array of nanostructures with arbitrary rotation angles, captures the image, which is then reconstructed to produce an output image that closely approximates the quality of the original “ground truth” image. Credit: Advanced Photonics (2024). DOI: 10.1117/1.AP.6.6.066002 Modern imaging systems, such as those used in smartphones, virtual reality (VR), and augmented reality (AR) devices, are constantly…

Composite metalens enables distortion-free imaging over a wide field of view.
(a) Singlet metalenses undergoes large barrel distortion. (b) Composite metalens effectively eliminates barrel distortion. (c,d) Raytracing modeling of (c) singlets and (d) composite metalens. The angle of incidence of light (in air) varies between 0° and 70° in 10° steps. Credit: Hanyu Zheng et al. In a recent study, researchers developed a composite metalens that enables distortion-free imaging. The study,…
