From 1 May to 30 June, visitors to the ‘Vintage Lasers and Holograms’ exhibition in Tempe, Arizona will have the opportunity to delve into the evolution of lasers, and the role they played in the academic and commercial evolution of holography.

Few overt security devices have been deployed as widely and successfully as security holograms – or DOVIDs (Diffractive Optically Variable Image Devices), to be more precise and inclusive.

Holography, long admired for its ability to capture and replay large amounts of optical information, is now breaking new ground in neuroscience, promising fresh insights into brain function and communication.

A team of scientists from Nanjing University and Tianjin University in China, and the National University of Singapore, have developed a novel method for controlling the polarisation of light using liquid crystal (LC) holography.

Holography has long tantalised scientists and engineers with its promise of creating immersive, lifelike 3D representations of real scenes.

In this most recent roundup of the use of holography in various healthcare settings (see also HN April 2021, July 2022, and September 2022), we report on two current innovations in the field of patient care.

Idvac Ltd, based in Manchester, UK, has introduced an innovative method for creating bespoke gold colour metallised films, completely free from pigments, inks, or dyes.

Vinyl records have experienced a resurgence in popularity in recent years, fuelled by a renewed appreciation of analogue sound quality and tangible music experiences. Amidst this resurgence, IQ Structures has unveiled an innovation in vinyl record production: IQ Vinyl.

A team of researchers at Pohang University of Science and Technology (POSTECH) in South Korea, led by Prof Junsuk Rho and PhD candidate Joohoon Kim, have announced a major breakthrough in the development of angle-dependent holographic displays that could redefine human interaction with digital information. The technology allows holograms to display multiple images based on the observer’s viewing angle.

IQ Structures, a research and manufacturing organisation focused on controlled nanostructures, has started using artificial intelligence (AI) to support its creative staff during the design of its DOVIDs (diffractive optically variable image device).
