Rochester Cloak is actually not an invisibility cloak that the Harry Potter character uses. This is a device that is used by eye specialists when examining patients. When an object is placed behind multiple layers of lens, it will disappear in the viewer's eyes, similar to the effect of the invisibility cloak.

In the study, experts performed stealth experiments with hands, faces and a ruler. Observers do not see the object even though they are present in reality.

According to Reuters, the world's science has introduced a number of sophisticated, expensive methods of stealth, but can not hide objects in three dimensions when viewed at different angles.

"Since then, we've found that this is the first stealth device that can make an object go away in a three-dimensional fashion on a continuous basis," said Joseph Choi, a member of the University of Rochester team. . This method can be applied in surgery, military or interior design, art.

Invisibility is the process by which an object is hidden in the viewer's eyes, while everything around it remains in the normal state.
