Abstract
AbstractMetalenses, in order to compete with conventional bulk optics in commercial imaging systems, often require large field of view (FOV) and broadband operation simultaneously. However, the strong chromatic and coma aberrations present in common metalens designs have so far limited their widespread use. Stacking of metalenses as one of the possible solutions increases the overall complexity of the optical system and hinders the main benefits of reduced thickness and light weight. To tackle both issues, this study proposes a single‐layer imaging system utilizing a recently developed class of metalenses providing large FOV. Using it, full‐color imaging with a FOV of is demonstrated. This approach, empowered by computational imaging techniques, produces high‐quality images, both in terms of color reproduction and sharpness. Suitable for real‐time unpolarized light operation with the standard color filters present in prevalent camera systems, these results might enable a pathway for consumer electronics applications of this emerging technology.
