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 ...

Scientists have utilized holographic projections to achieve unprecedented resolution in a light-based 3D printing technique.

Swave’s laser-powered holographic display engine is compact and lightweight Swave Swave’s holographic extended reality (HXR) display should be lighter and more compact than the birdbath optics ...

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 ...

To put it as simply as possible, a holographic sight uses a laser and mirrors to project a hologram (the reticle) for the shooter’s eye without using the front glass. A red dot uses an LED emitter ...

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 ...

Scientists have discovered a way to make 3D printing faster and more precise using holograms. Traditional 3D printers build objects layer by layer, but a newer technique called tomographic volumetric ...

In a research paper published by Optica, the researchers behind the system revealed it combines artificial intelligence (AI) and laser-generated holograms to provide high-level data protection ...
