Formation of edge dislocation by the computer generated hologram
, 2015 The possibility of formation of the beam with edge dislocation, which is similar to the Crossed D = D sign•01(10) beam is considered. It is shown that such mode may be obtained due to the diffraction of Gaussian beam on the special binary computer ...

Monolithically 3D‐Printed Spectral‐Spatial Meta‐Authenticators
Advanced Materials, EarlyView.A single height map printed in a low‐index resin by two‐photon lithography encodes multiple visible wavelengths in one metasurface without any polarization optics. A fabrication‐aware optimization folds the printable height levels into the design, so the device is printed as optimized.

Wood‐Derived Nanocellulose‐Biocarbon Fresnel‐Zone Plate Lenses for Sub‐THz Frequency Applications
Advanced Materials Technologies, EarlyView.Wood‐derived nanocellulose and lignin‐based biocarbon were combined to fabricate fully bio‐based Fresnel zone plate (FZP) lenses for sub‐terahertz frequencies. These sustainable FZP lenses exhibit low dielectric loss and high directivity, achieving performance comparable to that of metallic references, and remain functional under environmental stress ...

Time-Division Color Holographic Projection in Large Size Using a Digital Micromirror Device
Applied Sciences, 2021 Holographic projection is a simple projection as it enlarges or reduces reconstructed images without using a zoom lens. However, one major problem associated with this projection is the deterioration of image quality as the reconstructed image enlarges ...

A Simiple Method to Speed up the Calculation of a Computer-Generated Hologram
, 2011 The calculation speed is one of most dofficult problems for a computer-generated hologram of an object. This is due to the facts that both the pixel number of an object and that of the hologram are very large.
