ABSTRACT:
The abstract of this paper is the working principle of a Harry Potter-like invisibility cloak.
In order to make the cloak invisible, Light from all directions travel through the object, rather than hitting it.
Because of not being able to interact with light, the hidden object is therefore made invisible.
Optical Camouflage:
Active camouflage provides concealment in two important ways: firstly, it makes the camouflaged object appear not merely similar to its surroundings, but effectively invisible through the

Just how does augmented reality technology turn this odd shopping list into a recipe for invisibility?
First, let's take a closer look at the raincoat: It's made from retro-reflective material. This high-tech fabric is covered with thousands and thousands of small beads. When light strikes one of these beads, the light rays bounce back exactly in the same direction from which they came.
To understand why this is unique, look at how light reflects off other types of surfaces. A rough surface creates a diffused reflection because the incident (incoming) light rays scatters in many different directions. A perfectly smooth surface, like that of a mirror, creates what is known as a specular reflection -- a reflection in which incident light rays and reflected light rays form the exact same angle with the mirror surface.
In retro-reflection, the glass beads act like prisms, bending the light rays by a process known as refraction. This causes the reflected light rays to travel back along the same path as the incident light rays. The result: An observer situated at the light source receives more of the reflected light and therefore sees a brighter

The concept is called mutual telexistence and essentially involves projecting a remote user's appearance onto a robot coated in retro-reflective material. Say a surgeon were operating on a patient via remote control robotic surgery. Mutual telexistence would provide the human doctors assisting the procedure with the perception that they're working with another human instead of a machine.
Right now, mutual telexistence is science fiction, but scientists continue to push the boundaries of the technology. For example, pervasive gaming is already becoming a reality. Pervasive gaming extends gaming experiences out into the real world, whether on city streets or in remote wilderness. Players with mobile displays move through the world while sensors capture information about their environment, including their location. This information delivers a gaming experience that changes according to where users are and what they are doing.
Optical camouflage is just one method of creating the sensation of invisibility. On the next few pages, we'll explore the latest breakthroughs in the science of disappearing.
