The Future of Security Holograms Looks Bright, with Scattered Showers

For a technology that has seen its own fair share of change since its commercial inception in the 1980s, holography has established itself as a vital part of several industry sectors; most prominently in security print, brand protection, testing and monitoring, head-up displays and most recently as an enabler of virtual and augmented realities.

Holography Goes to the Movies

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?

Structural Colour Gets Special Attention at ODDS 2022

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.

Polarization Holography – a New Field of Holographic Research

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.

IHMA Members Hear About It First!

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.

What’s in a Name?

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’.

Increasing the Size of Displays with Stackable ‘Holobricks’

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.
