As was evident by the number of booths displaying augmented reality (AR) glasses and AR head-up displays (HUDs) at CES 2024, the two technologies are set to make a big impact in the consumer electronics market. These cutting-edge technologies share many similarities, but also exhibit distinct differences. A recent blog post by UK-based Envisics1 compares and contrasts the two technologies, with particular focus on their use of holographic optical elements (HOEs).

Researchers are one step closer to a new era of immersive displays as they use holography to blend the real and virtual worlds that can be viewed through ordinary eyeglasses. This advance, spearheaded by Princeton University researchers and reported on the university website, promises to revolutionise how we experience visual media.

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.

Lighting has long been acknowledged as a key element in shaping the atmosphere of any event, and recent advances in technology have brought innovative approaches to transform spaces into captivating 3D experiences.

Researchers from the Universities of Cambridge, Oxford and University College London have developed an advanced augmented reality (AR) holographic system that projects 4K video using LiDAR point clouds, specifically designed for automotive head-up displays.

The stakes are high in the race for lightweight, energy efficient waveguides for smart glasses. In this article adapted from ZDNet, Israeli augmented reality optics company Lumus explains why it believes its range of reflective 2D waveguide technology beats the diffractive competition.

Dr Alan Hodgson, a consultant in technologies for secure documents, looks at the implications of the evolution of the Metaverse from the perspective of holography and 3D displays.

Cambridge (UK) – based VividQ has announced the launch of its latest technology, unveiled for the first time at the recent SID Display Week Conference in San Jose, California.

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’.

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.
