Displaying real 3-D object images using a computer-generated hologram : a thesis presented in partial fulfillment of the requirements for the degree of Master of Science in Computer Science at Massey University [PDF]
, 1998 The magic of an optical hologram that produced by optical system offer us a never ending sense of wonderment. The images reconstructed from an optical hologram exhibit all of the three dimensional properties with full, rich perspective effects, enabling ...

Novel Functional Materials via 3D Printing by Vat Photopolymerization
Advanced Functional Materials, EarlyView.This Perspective systematically analyzes strategies for incorporating functionalities into 3D‐printed materials via Vat Photopolymerization (VP). It explores the spectrum of achievable functionalities in recently reported novel materials—such as conductive, energy‐storing, biodegradable, stimuli‐responsive, self‐healing, shape‐memory, biomaterials, and

Obtención de una placa fotosensible como material de registro holográfico
Boletín de la Sociedad Española de Cerámica y Vidrio, 2000 In this article was showed the procedure of obtaining and depositing of photosensitive dry films uses as holographic recording materials. We compare the thickness and the uniformity of plates obtained with two different depositing method, with a manual ...

Continuous Depth Control of Phase-Only Hologram With Depth Embedding Block
IEEE Photonics Journal, 2022 Digital holography is a promising candidate for advanced display, although several obstacles remain, such as the problem of heavy time consumption in the generation of phase-only holograms.

Electrical fixing of photorefractive holograms in Sr0.75Ba0.25Nb2O6 [PDF]
, 1993 Photorefractive holograms stored in Sr0.75Ba0.25Nb2O6 crystals are electrically fixed at room temperature. The fixed holograms can be read out directly or after a positive-voltage pulse is applied that can dramatically enhance the diffraction efficiency.

Meniscus Pixel Printing for Contact‐Lens Vision Sensing and Robotic Control
Advanced Functional Materials, EarlyView.A visual‐sensing contact lens is enabled by meniscus pixel printing (MPP), which rapidly patterns a 200 µm perovskite photodetector pixel in 1 s without masks, vacuum processing, or bulky equipment. A deep‐learning‐based super‐resolution reconstructs sparse on‐lens signals into 80 × 80 high‐resolution visual information, while AI‐driven eye‐tracking ...

Proceedings of International Workshop on QCD Green’s Functions, Confinement and Phenomenology — PoS(QCD-TNT09), 2010 We review our recent work on four topics in strong-interaction physics from the perspective of the gauge/gravity correspondence. In particular, we discuss (i) the construction of the ``metric soft wall'' dual for holographic QCD which reproduces the observed linear square-mass trajectories of radially and orbitally excited (light-quark) hadrons, (ii ...

Metachromatic Butterfly Bile Pigments for Multi‐Level Optical Security Films
Advanced Functional Materials, EarlyView.Bio‐derived optical security materials are manufactured by embedding butterfly‐based pigments in polymer films. Tunable color and fluorescence responses arise from concentration‐controlled metachromasy, enabling spatially encoded patterns with distinct visible, UV‐active, and spectral signatures.

Physical Review A, 2010 We propose a new scheme for parallel spatially multimode quantum memory for light. The scheme is based on counter-propagating quantum signal wave and strong classical reference wave, like in a classical volume hologram, and therefore can be called a quantum volume hologram.
