There are four items to report in this round up of recent banknote issues using holographic, or other diffractive optically variable, features.

A little known, but curious, use of a hologram’s ability to reconstruct an image as if it were ‘floating’ in space, is for holographic rifle sights. So how does this relatively new type of aiming system work and what are the advantages and disadvantages?

A technology talk given by a team of researchers from Stanford Computational Imaging Lab at SIGGRAPH 2022 reports on potential improvements to near-eye holographic displays.

Australian company Caps & Closures, which designs and manufactures plastic packaging, has launched the ID-Shield holographic labelling and decoration system. According to Caps & Closures, the labelling solution is fully integrated into the packaging as it is manufactured, with no added materials, adhesives, inks or printing processes.

Tracking down and responding to tenders is the life blood of sales departments in companies of all sizes. Getting hold of tender documents as quickly as possible after their publication can often be the difference between putting together a winning proposal and regretting you didn’t get the tender documents a few days earlier.

The holography industry creates spectacular imagery for applications in art, science and technology. To do this, the industry has developed an intricate jigsaw of equipment, know-how and people.

Anyone looking for a whistle stop literary tour of the milestones that map out the history of holography are fortunate, as two articles have appeared this month that chart the course of the technology – from before Gabor’s invention to future applications in the Metaverse.

Established in 1993, the HIR was one of the first projects undertaken by the IHMA and has been referred to as the association’s ‘Crown Jewels’. The number of registrations on the register has now passed the incredible figure of 10,000.

A topic that continuously grates on some within the holography community is the corruption of the term ‘hologram’ to apply to any display or image that heightens the sense of solidity or depth. For that group of holographers, there is some guidance and perhaps reassurance from a new research paper from the Changchun Institute of Optics, Fine Mechanics and Physics, China.

If, like me, you remember the start of 2021 as a time of reserved optimism in thinking that the year ahead couldn’t possibly be as bad as the year just passed, well you and I were only partially correct. 2021 proved to be as unpredictable in terms of mutations and variations of COVID as 2020. But as the following year in headlines show, the holography industry has proven to be incredibly resilient in the face of economic and societal turbulence.
