Researchers designed a computational framework that consists of a compact metalens-integrated microscope and a transformer-based neural network, which enables large FOV and subpixel resolution imaging ...

In a recent study, researchers have developed a compound metalens that enables distortion-free imaging. The study, published in Engineering, presents a novel approach to on-demand distortion ...

(a) A singlet metalens suffers from large barrel distortion. (b) A compound metalens effectively eliminates the barrel distortion. (c, d) Ray-tracing modeling of the (c) singlet and (d) compound ...
