First, you probably want a DIY hologram kit since it will come with the exposure plate and a known-good light source. Far be it for us to tell you you can’t buy plates and a laser pointer to ...

The DHI system operates by actively illuminating the tissue with a laser and recording the light scattered from ... for ...

A major driver for the development of holographic photopolymers was the concept of optically storing data in a 3D volume. The traditional approach to this problem was to spatially modulate a laser ...

The hologram show uses a new "depth" technology that makes the animals seem big. The moving images are brought to life by a laser projector containing crystals that let simple sunglasses worn by ...

meaning you can see its holographic projections using air as the medium. Here's how it works. The machine uses a 1kHz pulse laser and sends the laser through a 3D scanner, which reflects and ...

Researchers have invented a new way to align 3D semiconductor chips by shining a laser through concentric metalenses patterned on the chips to produce a hologram. Their work can help to lower the ...

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 ...

Pyramid laser displays are among the exhibits at this year's Dreamy Place festivals in Brighton and Crawley Laser pyramid sculptures, holograms and an array of sound installations are set to ...
