Vectorized holographic color prints using superpixelated metasurface
Photonic and Phononic Properties of Engineered Nanostructures XI, 2021Metasurface, 2D counterpart of metamaterials, has been of great interests due to its capability of manipulating light’ properties such as amplitude, phase, polarization, and angular momentum. Individual property of light is quite freely modulated using metasurface; modulation of the several properties in single metasurface has been intensively explored.

Printed Circuit Board Evaluation by Holographic Interferometry
Review of Scientific Instruments, 1972Application of real time holographic interferometry for the examination of a printed circuit board is described. The procedures and the resulting holographic interferograms of two specific studies are presented: (1) The heat conduction of a spacer used for mounting transistors on a heat sink, and (2) the detection of inner layer short circuits on a ...

Printing Of Holographic Stereogram Using Liquid-Crystal TV
SPIE Proceedings, 1989Multiplrex Holograms are printed by using a liquid-crystal television receiver as a spatial light modulator instead of silver-halide movie film. Reconstructed 3-D images of wire-frame model can be observed with high contrast. But, some noise which is caused by LCTV is also observed.

Dual-Polarization Printed Holographic Multibeam Metasurface Antenna
IEEE Antennas and Wireless Propagation Letters, 2017Multibeam antennas have emerged as a promising concept for applications where selective beam coverage is required. Multibeam radiation can be achieved leveraging the concept of metasurfaces, enabling the radiated wavefronts to be tailored in an all-electronic manner, making reconfigurable multibeam operation possible without the need for bulky feeding ...

Holographic stereogram printing under the non-vibration environment
SPIE Proceedings, 2014Printing the holographic stereogram (HS) is vulnerable to the vibration when the holographic film is exposed to the continuous wave laser beam compared to the pulsed laser. The continuous wave laser is required to be more longer exposed to the holographic film for forming the fringe pattern, hence the optical system is normally set up on the ...

Generation of Phase Data for Holographic Stereogram Printing on a Photoresist
Digital Holography and Three-Dimensional Imaging, 2017The paper proposes encoding of directional information extracted from perspective images of 3D objects as phase holograms for holographic stereogram printing on a photoresist. Such printing allows for mass production of holograms.
