Rather than using camouflage, transparent panels, or Predator-style light-bending materials, Phantom Twist exploits motion blur and the limits of human vision.

Researchers demonstrate that something interesting happens when a small drone with a spindly airframe spins at a high speed: it very nearly turns invisible. The spidery device is…

The drone chassis spins at 25 RPM and, thanks to a quirk of human vision, it appears like a faint smudge in the air.

Instead of costly camouflage or advanced stealth technology, Northwestern University researchers designed a drone whose entire body spins up to 25 times per second, turning it…

Rather than using camouflage, transparent panels, or Predator-style light-bending materials, Phantom Twist exploits motion blur and the limits of human vision.

Un gruppo di ricercatori della Northwestern University ha sviluppato un drone, denominato 'Phantom Twist', che sfruttando un principio ottico della visione umana, diviene quasi…

We’re sure that only good will come of this.
