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 ...

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 ...

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 ...

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 ...

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 ...

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

Meanwhile, metasurfaces—ultrathin optical devices—are known for their ability to encode vast amounts of information, allowing ...

3D object created from a hologram. Traditional tomographic volumetric additive manufacturing (TVAM) uses laser light to solidify resin in a rotating vial. However, this method is inefficient, with ...

(Nanowerk News) While traditional 3D printers work by depositing layers of material, tomographic volumetric additive manufacturing (TVAM) involves shining laser light at a rotating vial of resin until ...
