Harry Potter's fabulous invisibility cloak is gradually becoming a reality. The British startup Invisibility Shield announced the creation of a material, behind which, any objects become invisible.

To earn on further research, the company posted their invention on Kickstarter. You can become the owner of a rectangular shield made of a miracle material measuring 90 x 60 cm for $ 400.

One of its main advantages is the ability to work without a power source. And yet the technology used here is just an ingenious optical trick, a kind of funny engineering. The shield, using a precision lens array, directs most of the light reflected from the object away from the observer. Thus, the object hidden behind the shield becomes virtually invisible.

The shield is not able to perfectly reproduce the “picture” behind the hidden object. As a result, it is a kind of blurry image.

According to the developers on Kickstarter, the greatest effect is achieved on uniform backgrounds – for example, against the background of leaves, grass, sand, sky and rails. Оптический щит
