Could Holographic Police Officers Help Keep the Peace?

In the 2014 Hollywood movie RoboCop, a detective becomes critically injured and is turned into a cyborg police officer whose programming blurs the line between man and machine. In his on-line opinion piece on the ‘Police1’ platform , Commander Jason Grossini looks to holographic, rather than robotic, police officers to keep the peace.

Holographic Technology Helps Find Needle in a Haystack

Researchers at MIT (Massachusetts Institute of Technology) have invented an augmented reality headset that uses holographic principles to allow humans to ‘see’ through opaque surfaces. The invention, dubbed ‘X-AR’, combines wireless sensing with computer vision and a floating holographic sphere to enable users to see hidden items.

BOBST – Still Innovating After All These Years

Ever since surface relief replication became the preferred means of mass production for holography, hot-stamping foil has been a principal method of application – particularly for packaging and secure documents. The machines used to apply holograms at speed and in register are an integral part of the job’s final appearance. Swiss machinery manufacturer, BOBST, has been involved in providing hot-stamp presses to the holography industry for many years, and continues to innovate to this day.

Euclideon Changes Name and Adds New Applications

A few years ago, Australia based Euclideon Holographics made the news with the production of its multi-user hologram table, which allowed four people to interact simultaneously with images apparently projected onto a table surface (see HN September 2021). Since then the company has changed its name (to Axiom Holographics) and added new applications to its product offerings.

The Making of a Mona Lisa Hologram

Leonardo da Vinci’s portrait of the Mona Lisa is one of the most readily recognisable works in western art. A group of research institutes have now collaborated to develop an acoustic metasurface-based holography technique that uses a deep learning algorithm to generate and iteratively improve a hologram of the portrait.

When Holograms Disappoint

It used to be that poor lighting was the major cause of disappointment when it came to viewing holograms. But as the definition of holography has been stretched to include heightened reality displays, so have the number of reasons to be disappointed.
