Non-local metasurfaces for spectrally decoupled wavefront manipulation and eye tracking

Nature Nanotechnology, 2021
Metasurface-based optical elements typically manipulate light waves by imparting space-variant changes in the amplitude and phase with a dense array of scattering nanostructures.

Wavefront guided ablation

American Journal of Ophthalmology, 2001
A DAPTIVE OPTICS WAS FIRST SUGGESTED IN 1953 BY astronomer Horace Babcock to remove the blurring effects of turbulence in the atmosphere on telescopic images of stars.1 The U.S. Defense Department later invested heavily in the development of adaptive optics technology to improve the effectiveness of laser weapons as part of its Star Wars Program.

High-efficiency ultrathin terahertz geometric metasurface for full-space wavefront manipulation at two frequencies

Journal of Physics D: Applied Physics, 2020
It has been demonstrated that metasurfaces have the ability to manipulate the wavefront. However, most multifunctional metasurfaces reported to date only operate in either reflection or transmission mode.

Off-axis digital holographic multiplexing for rapid wavefront acquisition and processing

Advances in Optics and Photonics, 2020
Off-axis holographic multiplexing involves capturing several complex wavefronts, each encoded into off-axis holograms with different interference fringe orientations, simultaneously, with a single camera acquisition.

Broadband high-efficiency cross-polarization conversion and multi-functional wavefront manipulation based on chiral structure metasurface for terahertz wave

Journal of Physics D: Applied Physics, 2019
In this paper, a broadband and high-efficient tri-layered chiral structure metasurface (CSM) for linear polarization conversion and multi-functional wavefront manipulation was proposed and investigated numerically in terahertz region.
