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.

Researchers at KTU (Kaunas University of Technology) Institute of Material Science in Lithuania have developed a new method to produce holographic security labels combining dot-matrix and e-beam.

The International Hologram Manufacturers Association (IHMA), which 20 years ago launched the Hologram Image Register (HIR) – often described as the ‘jewel in the crown’ for the trade body – has recently expanded the register to incorporate all optically v variable security images. The result is the Security Image Register (SIR), the only database of its kind for the security community, which safeguards copyright and helps deter attempt to copy security images, inadvertently or otherwise.

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.

Reconnaissance International has announced that the 2024 Holography Conference Online (THCO) will be held on 12-13 November. The call for papers is now open and delegates are invited to submit a proposal to present by 13 September 2024.

Researchers at the University of Tokyo have developed a full-colour 3D display method that utilises a smartphone screen rather than a laser to create holographic images. With further development, the new method can be used for augmented reality displays.

In June 2022, after the closure of Hologram Industries Research GmbH, a new company – Phoenix Holographix GmbH – was formed close to Munich, Germany.

Smart Engines, an AI developer, has unveiled an enhanced version of its AI system designed to detect forged documents, with a particular emphasis on holographic protection. The new technology allows for the rapid extraction of data from passports and ID cards while simultaneously verifying their authenticity. What sets this system apart is its ability to perform document verification in real-time video streams.

The International Hologram Manufacturer’s Association (IHMA) is stepping up its presence in China in a move to boost growth and promote the technology’s benefits to brand owners, government authorities and sector suppliers.

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.

As the number of stars and celebrities whose holopresence has been posthumously captured continues to increase, Holography News® reports on two famous performers that have recently been immortalised in light. And one that is on the brink.

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.

The International Hologram Manufacturers Association (IHMA) has announced a new chair and board members as it expands its operations.

Supplier of hot-stamping machinery, Gietz, has announced it has invested strategic venture capital in the Netherlands-based Vinfoil in order to strengthen the long- term stability of the company and its product portfolio.

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.

Following the launch of the International Hologram Manufacturers Association’s expanded Security Image Register (SIR) in January, a proposal was made to extend membership criteria and amend the IHMA articles of association to encompass all security OVD (optical variable device) suppliers. This has now been unanimously adopted.

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.
