3D printing by painting with light beams on a vat of liquid plastic was once the stuff of science fiction, but now is very much science-fact. More than that, it’s consumer-level technology that ...

Holographic disk drives have long promised to eclipse even the latest high-density optical storage media. Now finally, as Duncan Graham-Rowe reports, the promising three-dimensional approach to ...

On a flight from Amsterdam to Paris in 1965, French Astrophysicist Jacques Blamont had a sad tale to tell his traveling companion. Because of faulty equipment, every photographic plate of groups ...

A commercial holographic storage system requires a tunable, coherent laser source. Because holographic storage records throughout the volume of the medium and this volume can change ...
