A new publication from Opto-Electronic Advances; DOI 10.29026/oea.2026.250149, discusses a quarter-wave geometric-phase ...

(Nanowerk News) Everybody has seen holograms, on a bank note, a passport or in Star Wars. Holography is a powerful technique of photography of a light field without a lens for 3D imaging and display.

Electron holography is based on the fundamental principles of holography, which involves the recording and reconstruction of wavefronts. In holography, a hologram is created by capturing the ...

Akonia Holographics, a startup in Longmont, Colorado, spent years trying to make holographic data storage work. It didn’t succeed, but now it found a new use for the same technology. The company now ...

A holographic display developed by researchers at Samsung allows high-resolution 3D videos to be viewed from a variety of angles and could be made thin enough to be incorporated into a smartphone.

A new publication from Opto-Electronic Science; DOI 10.29026/oes.2022.220004 considers high frame-rate orbital-angular-momentum multiplexing holography. The development of mobile Internet, especially ...

Most people own at least one hologram, probably without knowing it’s a hologram. Those with relatively little optical background, most of the general public, are most likely to encounter real ...
