A meta-hologram consisting of sub-wavelength gold cross nanoantennas enables polarization-controlled dual images in the visible region.
A hybrid patterning system combining projection and interference lithography enables the fabrication of 14-inch 3D images.
A pre-processing procedure can diminish the data noise from new-generation hyperspectral sensors, thus minimizing negative impacts on target detection algorithms.
