Anyone who has been involved with holography for any length of time will have had periods of frustration with the technology. But the story of a Japanese man who literally fell out of love with his hologram wife is taking things to extremes.

In conventional holography, the polarization of the reference and object beams are arranged to be co-linear to achieve the maximum contrast of the interference fringes formed and record the greatest amounts of amplitude and phase information from the original object wave.

The International Hologram Manufacturers Association (IHMA) Patent Newsletter is a monthly review of patents issued in the fields of security, decorative and data storage holography, along with holographic techniques, processes and displays.

Whilst travel restrictions, due to the pandemic, have prevented many face- to-face sales activities in the holography industry, many companies have continued their research programmes behind closed doors. One such company is IQ Structures, which has continued to innovate its range of eye- catching optically variable features.

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.

Holography scientists, technologists and artists alike are often guilty of bemoaning the (mis)use of the term ‘holography’ to describe augmented and virtual reality (AR and VR) displays such as HoloLens. But is there a case to say that depictions of holograms on film, TV and other ‘flat’ media have actually foreseen, and perhaps motivated, developments in 3D imaging techniques?

The phenomena of structural colour – when different wavelengths of light are selectively reflected from a substance, with the remaining wavelengths transmitted or absorbed – is gaining increased attention in the security print industry as an environmentally benign method of creating colour without resorting to dyes or other chemicals.

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.

Subscription service ESPN+ has streamed what they claim to be the world’s first tennis match featuring a real person versus a virtual player. In the match streamed on 7 May, John McEnroe faced off against his younger self – represented by a virtual player powered by artificial intelligence (AI).

Shriram Veritech Solutions was founded in 1992 and is a part of the Shriram Group of companies, one of the largest industrial houses in India. Over the years, Shriram Veritech has built a range of products over the years including holograms, labels and stamping foils to decorate and protect products.

Experts, government representatives, technologists and commentators gathered in Austria’s stunning capital city of Vienna (11-13 April) to share recent technical developments in the fields of optical and digital document security.

The use of the term ‘holography’ to describe phenomena other than wavefront reconstruction is now well established in the media. Often, the purpose of using the term is to convey a sense of futuristic heightened reality, which can be frustrating to holography purists but could also be seen as praise if you believe the idiom ‘imitation is the sincerest form of flattery’.

West Midlands Police (UK) have released information on what to do if you think you have come across a fake banknote, after a video was posted online showing a counterfeit £20 on which the hologram stripe had been simulated by a sticker.

After the initial wave of commercial applications of holography in the early 1980s the holographic industry, at least for transfer films and labels, was spread across four distinct areas of competence: origination, mass-production, converting and application & finishing.

The International Hologram Manufacturers Association (IHMA) Patent Newsletter is a monthly review of patents issued in the fields of security, decorative and data storage holography, along with holographic techniques, processes and displays.

Meta Materials Inc, a developer of high-performance functional materials and nanocomposites, announced it has acquired Plasma App Ltd (PAL), in a stock for stock transaction valued at $20 million.

Holograms have been used, for some time, to aid medical and nursing students in learning medical procedures and studying anatomical structures. And now, tech giant Cisco has redeployed its Webex platform to further the use of holograms for medical applications.

Researchers have developed a new method to display holographic images using ‘holobricks’ that can be stacked together to generate large-scale holograms. The researchers, from the University of Cambridge and Disney Research, have developed a holobrick proof-of-concept, which can tile holograms together to form a large seamless 3D image.

Previously, Holography News® has reported on the differing approaches that companies are following to manufacture wearable virtual reality and augmented reality headsets as entry devices to access the Metaverse – the network creating a virtual 3D world.
