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 ...

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 ...

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 ...

Controlling a computer with your mind was once pure science fiction, but it's now plausible thanks to brain-computer ...

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 ...

Here’s a whirlwind tour of some of my favorites. On that list are a POV holographic display, giant cast-resin LEDs, an optical-pump ruby laser built out of parts from AliExpress, blinky goodness ...
