Optical holography is a promising technique to achieve a naked-eye 3D display.However,the narrow viewing angle and chromatic aberration are the two key issues that usually limit the holographic display performance.A r...
Diffractive liquid-crystal optics is a promising optical element for virtual reality(VR)and mixed reality as it provides an ultrathin formfactor and lightweight for human factors and ergonomics.However,its severe chro...
funding from the European Union's Horizon 2020 research and innovation program under the Marie Sktodowska-Curie grant agreement No 884104(PSIFELLOW--3i);funding through the Swiss Nanoscience Institute Argovia project 16.01 ACHROMATIX.Parts of this research were carried out at beamline PO6 at PETRA I,DESY(Hamburg,Germany),a member of the Helmholtz Association HGF(proposal I-20210938 EC);supported in part by the Maxwell computational resources operated at Deutsches Elektronen-Synchrotron DESY,Hamburg,Germany.
Achromatic doublets are combinations of two individual lenses designed to focus different wavelengths of light in the same position.Apochromatic optics are improved versions of the achromatic schemes which extend the ...
A new framework of light coherence optimization is proposed to design non-ideal broadband achromatic lenses,enabling large-scale flat lenses'implementation and high performance.The strategy paves the way for practical...
