Metalenses have been used to image microscopic features of tissue and resolve details smaller than a wavelength of light. Now, Harvard researchers have turned the metalens towards space. Researchers ...
(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 ...
Researchers have developed a 10-centimeter-diameter glass metalens that can image the sun, the moon and distant nebulae with high resolution. It is the first all-glass, large-scale metalens in the ...
In a new publication from Opto-Electronic Advances; DOI 10.29026/oea.2022.210062 , researchers from Tianjin University, China and Capital Normal University, China, discuss dynamic phase assembled ...
Researchers have leveraged deep learning techniques to enhance the image quality of a metalens camera. The new approach uses artificial intelligence to turn low-quality images into high-quality ones, ...
