Scientists at Stanford University have developed a shape-shifting material that can dynamically change both colour and surface texture, mimicking the camouflage abilities of cephalopods such as octopuses and cuttlefish. Published in Nature, this breakthrough could enable advanced optical security, adaptive displays, soft robotics, and next-generation anti-counterfeiting technologies.

Researchers at the UCLA Samueli School of Engineering have developed a novel light-programmed system capable of projecting high-resolution three-dimensional images across 28 depth layers simultaneously, marking a significant advance in holographic display technology. Published in Light: Science & Applications, the research introduces a hybrid digital-optical architecture that combines deep learning with diffractive optics to generate volumetric images in a single exposure.

Researchers at the Korea Advanced Institute of Science and Technology (KAIST) have created a new hologram technology that uses light’s own properties as an encryption key, posing a far greater challenge for those looking to counterfeit security features.

For many years, KURZ has led in demonstrating how advanced optical security technologies integrate into banknotes. Through a series of creative sample banknotes and showcases, the company has illustrated the potential of security threads, registered stripes, stripe-over-window features, applied patch labels, and security patches.

Security printing has always borrowed optical phenomena from physics and chemistry, and few are as useful as luminescence.

Idvac is a private company based at Manchester Science Park in the UK, founded in 2004 to develop new processes and products for holographic, packaging, and solar window films. It has now developed an innovative process that introduces enhanced design features for security holograms and optical films.

Since their use on credit cards in the 1980s, holograms have been associated with optical security. Their distinctive rainbow colour shifting on banknotes, passports, payment cards and branded packaging, offer a quick visual confirmation that an item is genuine.

Over the past few years, light-field imaging has been considered one of the more promising directions for next-generation document security features. By reproducing not only the intensity of light but also its direction, a light-field structure can create convincing 3D imagery that changes naturally when the viewing angle shifts. For the holder of a passport, banknote or ID card, the result is an effect that is both visually striking and immediately verifiable by the naked eye.

At the High Security Printing (HSP) Asia 2025 conference in Kuala Lumpur this month, Authentix unveiled PICO secure™, described as the world’s first nano-optic, plasmonic optical variable device (OVD) for polycarbonate identity documents. The feature – says Authentix – delivers always-on structural colour and movement, drawing on its award-winning nano-optic technology.

The European Technology Platform Photonics21 and some of Europe’s largest companies – including Bosch, Volkswagen, Mercedes-Benz, Nokia Bell Labs, Zeiss, Trumpf, and EssilorLuxottica – have united to urge the European Commission to prioritise photonics in the upcoming EU Framework Programme (FP10).
