3D laser holograms sound cool, but they're generally hot. As in, hot enough to burn your skin. But now researchers at the Digital Nature Group, a Japanese lab, say they've figured out a way to ...

To create their hologram, researchers fired their femtosecond laser through a spatial light modulator, which continues the beam through a series of lenses, a mirror and a Galvano scanner, which ...

The type of hologram that is created in the video is the simplest type, called a transmission hologram, as it requires a laser light to illuminate the holographic film from behind to recreate the ...

In my description of holography above, the 2D pattern is formed from two light fields: one has only scattered from the object and one has not scattered at all. This is why we use lasers: the laser ...

This holographic laser projector (HLP) projects images onto curved and tilted surfaces. We just got our hands on the tech in the back rooms of CES 2010, and it works beautifully.

To make a hologram of something like a 3D fingermark, researchers split light from a laser into two parts. One part, called the reference wave, shines directly on a digital camera.

K Laser Technology, a manufacturer of holographic and metalized substrates, is set to exhibit its offset KOLDfoil ONE and Viridian Eco-Paperboard substrates at Print UV 2023.

K Laser Technology will be highlighting Viridian™ holographic eco-paperboard®, a fully recyclable and sustainable, yet luxurious and stunning alternative to laminated product packaging.

Holograms are strange, ghostly, 3-D images on glass or film. ... And because they can be seen only when lit by a laser or by highly focused incandescent light, she added, ...
