An aerial laser display capable of projecting 3D-images in mid-air

While I’m sure this device, if used in close proximity to a human being, would result in an industrial-strength sunburn, I welcome any technology that brings us close to a real-life holodeck. The Aerial Burton is a 3D display that works by firing a laser pulse into a 3D scanner, and then ionizing the air at specific points, which makes a very bright point of plasma, and by creating several of these points, the device can create a 3D object or text. While the full potential for such a display has yet to be seen, Asano suggests it could be used as a communication aid in the event of a disaster by communicating evacuation routes. I can certainly see the… Read More »An aerial laser display capable of projecting 3D-images in mid-air

Chauvet's new LEDs dim with an external dimmer

Oooh, this is cool. Chauvet has introduced two new LED fixtures that dims with an external dimmer, instead of needing DMX directly, though you can dim it that way, too: This is a really brilliant idea, because you just directly swap your old Altman ellipsoidal or Fresnel onto the circuit and get the full benefits of LED, without needing to run a DMX line up to the unit. I hope this speeds along adoption of LED tech, because all those incandescent lamps burning waste so much energy that it’s almost obscene. The faster we can get rid of incandescent, the better.
