Full-Color See-Through Three-Dimensional Display Method Based on Volume Holography
Sensors, 2021 We propose a full-color see-through three-dimensional (3D) display method based on volume holography. This method is based on real object interference, avoiding the device limitation of spatial light modulator (SLM).

3D Capture and 3D Contents Generation for Holographic Displays
Imaging and Applied Optics 2016, 2016 Methods for generation of 3D contents for holographic displays and printers with focus on capture/display parameters adjustment are discussed. Input data for the generation process are captured by means of digital holography and profilometry/tomography or are acquired as multiple perspective images or are extracted from a computer graphic model ...

All‐Optical Reconfigurable Physical Unclonable Function for Sustainable Security
Advanced Materials, EarlyView.An all‐optical reconfigurable physical unclonable function (PUF) is demonstrated using plasmonic coupling–induced sintering of optically trapped gold nanoparticles, where Brownian motion serves as a robust entropy source. The resulting optical PUF exhibits high encoding density, strong resistance to modeling attacks, and practical authentication ...

Dual-View Integral Imaging 3D Display Based on Multiplexed Lens-Array Holographic Optical Element
Applied Sciences, 2019 We propose a dual-view integral imaging 3D display based on a multiplexed lens-array holographic optical element (MHOE). A MHOE is a volume holographic optical element obtained by multiplexing technology, which can be used for dual-view integral imaging ...

Advanced Materials Technologies, EarlyView.One‐dimensional C4N2H14PbBr4 is shown to have a quasi‐direct electronic band structure and strongly anisotropic transport with polarized broadband emission. A GW/Bethe–Salpeter excited‐state force formalism, supported by polarized Raman and temperature‐dependent photoluminescence, identifies low–frequency Pb–Br phonons that drive ultrafast exciton self‐

Holographic Near-Eye 3D Display Method Based on Large-Size Hologram
Frontiers in Materials, 2021 In this paper, we propose a holographic near-eye 3D display method based on large-size computer-generated hologram (CGH). The reconstructed image with a large viewing angle is obtained by using a time multiplexing and spatial tiling system.
