Hologram-like device animates objects using ultrasound waves
theguardian.com- New type of hologram uses ultrasound waves to trace 3D objects with a tiny polystyrene grain.
- It can trace an object within one-tenth of a second, making the movement of the grain completely invisible to our eyes, and leaving just the visualised object.
- The device relies on two horizontal plates which control the movement of the grain, and built-in LED lights that add color to the objects.
- This is a promising technology which, in the far future, could lead to 3D holograms which look like real objects.
