A London-based company has figured out the technology needed to build an invisibility shield that can help you spring a surprise on your friends. Not just that, you can get your hands on its later this year, if you pledge your support to their Kickstarter campaign.
London-based Invisibility Shield Co., picked up the mantle and surged ahead with ideas they had, failed miserably, but never gave up. Almost two years later, they have settled upon a reliable and efficient mechanism to make large yet light invisibility shields that could be at your doorstep in time for Christmas.
The technology behind the function of the shield is fairly simple. A precision-engineered lens array works to deflect light from the subject (behind the shield), away from the observer (in front of the shield).
The lenses are oriented vertically to allow light from the subject to diffuse when it passes through the shield. The light from the subject’s background is refracted towards the observer who cannot spot the subject hiding behind the shield.
The shield works best against uniform backgrounds such as foliage, grass, sand, and sky but will also work well against walls, painted lines, and rails, the company claims on its Kickstarter page.
