Becoming invisible is possible

Two companies are offering invisibility shields for two different uses.

The Canadian company HyperStealth Corp. succeeded in 2019 after nine years of research to develop a technology that allows making an object or a person placed behind the shield created by the company invisible. The result of invisibility is achieved by managing to deflect the path of light.

The people or objects behind the shield equipped with this technology are not illuminated. They are not visible. The HyperStealth company used the Snell-Descartes laws of the 17th century relating to the reflection and refraction of light rays to develop their project. The device is based on the principle of refraction of two materials, creating a blind spot for meditation and preventing light from passing through the shield.

The shield material also has the same principle as the lenticular lens that allows you to see an image only when you are placed in the right place, meaning that you can see something behind it but cannot distinguish its shape and nature. HyperStealth Corp. specializes in camouflage clothing and has filed a patent to protect this technology and start a manufacturing process, primarily for military use.

Invisibility Shield Co.

The British company Invisibility Shield Co. has launched an internet crowdfunding to commercialize invisibility shields and has already managed to raise €80,000 in March 2022, 53 days before the end of pre-sales. The company will propose sending its buyers an invisibility shield for playful use. Currently, only twenty-five prototypes are working, and this collection will allow the product to be marketed on a large scale.

The device looks like a semi-transparent glass that can be placed in any environment. It works in complete autonomy because the glass relies on a network of optical lenses that play on the refraction of light to make objects placed behind disappear. The network of lenses is designed to direct a large part of the light reflected by the observed subject away from the observer by sending it laterally to the left or right. The light becomes very diffuse as it passes through the shield’s background.

From the observer’s perspective, this light is spread horizontally across the front of the security, preventing the subject from being seen where it would typically be. The use of lenses to play with the properties of light has been used in many devices such as cameras, microscopes, and telescopes in the past and more recently, companies are moving towards new shield-type products. For example, Invisibility Shield Co. offers its shield for €359 for a dimension of 95×65 cm.
