called a transmission hologram, as it requires a laser light to illuminate the holographic film from behind to recreate the scene. This contrasts with a white light reflection hologram ...

Quantum entanglement, one of the strangest and most powerful aspects of physics, has just been taken to a new level with the ...

A research team led by Stelios Tzortzakis at the Institute of Electronic Structure and Laser in Greece has developed a new optical encryption system. This system encodes information as holograms ...

In holographic storage, light from a coherent laser source is split into two beams, the signal (data-encoded) and reference beams. These two beams are recombined to overlap through the volume of ...

The security holograms market share analysis is poised for significant expansion, projected to surpass USD 9536.7 million by ...

Unlike other optical media, such as CDs and DVDs, InPhase's holographic disk is not spun continuously during reading or writing. Instead the disk remains stationary while a blue laser (of ...

Recently IEESpectrum reports some promising work using holographic imaging to generate nanoscale structures at record speed. Current stereolithography printers make use of UV laser scanned over ...

Meanwhile, metasurfaces—ultrathin optical devices—are known for their ability to encode vast amounts of information, allowing the creation of high-resolution holograms. By combining metasurfaces with ...

Experiments with monkeys have identified the brain areas involved in the recall of various learned tasks. Memory may take the form of interference patterns that resemble laser-produced holograms ...
