When the image takes over the real: Holography and its potential within acts of visual documentation [PDF]

, 2020
In Camera Lucida, Roland Barthes discusses the capacity of the photographic image to represent “flat death”. Documentation of an event, happening, or time is traditionally reliant on the photographic to determine its ephemeral existence and to secure its

"Hologram" ocalałego. Rozpoznanie

Widok. Teorie i Praktyki Kultury Wizualnej, 2022
Celem artykułu jest opis i analiza USC Shoah Foundation Dimensions in Testimony - projektu zapoczątkowanego w 2012. Jest to inicjatywa mająca na celu rejestrację ocalałych w postaci hologramów 3D, a zarazem pierwszy tak interaktywny program pytań i odpowiedzi w czasie rzeczywistym wykorzystywany w narracji o Holokauście.

Fixing of photorefractive volume holograms in K1-yLiyTa1-xO3 [PDF]

, 1995
We report the f ixing of photorefractive holographic gratings with high eff iciency in a sample of K1-yLiyTa1-xNbxO3 doped with Cu, V, and Ti. Holograms are thermally fixed through the screening of a photorefractive space-charge field by a nonphotoactive

Structure and singly occupied molecular orbital analysis of anionic tautomers of guanine [PDF]

, 2008
Recently we reported the discovery of adiabatically bound anions of guanine which might be involved in the processes of DNA damage by low-energy electrons and in charge transfer through DNA.

Spectrally Tunable 2D Material‐Based Infrared Photodetectors for Intelligent Optoelectronics

Advanced Functional Materials, EarlyView.
Intelligent optoelectronics through spectral engineering of 2D material‐based infrared photodetectors. Abstract The evolution of intelligent optoelectronic systems is driven by artificial intelligence (AI). However, their practical realization hinges on the ability to dynamically capture and process optical signals across a broad infrared (IR) spectrum.

Multilayer Soft Photonic Arrays Inspired by Cephalopod Skin for High‐Density, Independent, and Multimodal Actuation

Advanced Functional Materials, EarlyView.
A vertically stacked, DEA‐driven photonic array inspired by cephalopod skin, featuring highly crystalline colloidal crystal gels with vivid color, low FWHM and scalability is presented. The multilayer design removes lateral pixel interference, achieving near‐100% fill factor with fully independent RGB actuation.
