Chinese professor unveils 'Harry Potter' invisibility cloaking

From Superinnovators 04/12/23

Chinese Academy of Sciences Prof. Chu Junhao unveiled his invisibility cloak technology on 28th October at a Super Science Night event hosted by Chinese video-sharing platform Bilibili.

Using a panel with a lenticular grating of tiny cylindrical convex lenses, Chu made his lower body appear invisible, while the background remained visible.

This effect is achieved by the lenses’ ability to refract light, creating images too small for the eye to notice.

Chu said that in the future everyone will have a Harry Potter-style invisibility cloak in wardrobe.
