Researchers from the University of Science and Technology of China (USTC) have unveiled a planar optical device that ...

Abstract: For three-dimensional (3D) imaging based on fringe projection profilometry (FPP), maximum fringe frequency selection and fringe frequencies allocation have a significant impact on the ...

Abstract: Slanted photopolymer-based diffraction gratings can undergo instant and quantifiable analyte-induced changes in both grating diffraction efficiency and peak reconstruction wavelength. This ...

By controlling the energy of the Bessel beam, they precisely controlled the gap of the nano-grating ... the zero-level diffraction signal intensity was received with a power meter, and the attenuator ...

LLA: Lenticular lens array; MLA: Microlens array. To summarize, diffraction grating-based 3D displays have the advantages of minimum crosstalk, reduced vergence-accommodation conflict, tailorable view ...
