July 28 (UPI) --Eduardo Kac has been trying for 37 years to realize his vision for an art project he began when he was just 24 years old -- sending one of his holographic poems, or holopoems as he ...

To burn or write in the air, the pen emits high-intensity laser pulses to create ionized gas or plasma. In turn, this emits energy in the form of light. The pulses are brief, just femtoseconds, and ...

A project at the Australian Research Council Centre of Excellence for Transformative Meta-Optical Systems (TMOS) has developed a device that might ultimately allow live holography to be used in field ...

With recent advancements in artificial intelligence, it is predicted holograms will become an ever-greater part of our future lives. A type of image made with a laser, holograms can make objects ...

[The Thought Emporium] has been fascinated by holograms for a long time, and in all sorts of different ways. His ultimate goal right now is to work up to creating holograms using chocolate, but along ...

Tailored profiles: The working principle of the new metalaser. The designed geometric phase profile is introduced to the metasurface by rotating the hole in each silicon nitride nanodisk. Then the ...

Researchers from Cambridge and Light Blue Optics, Ltd. have developed a prototype pocket-sized, battery-powered video projector — or at least the technology that should, in the mythical two to five ...

Researchers have invented a new way to align 3D semiconductor chips by shining a laser through concentric metalenses patterned on the chips to produce a hologram. Their work can help to lower the cost ...

Holograms were invented in Rugby by scientist Dennis Gabor, who won the Nobel Prize for Physics in 1971 for the idea [Getty Images] With recent advancements in artificial intelligence, it is predicted ...
