Abstract—
This paper reviews how the original Telexistence (tele-existence) technology eloped, and describes a newly developed method of mutual
Telexistence using projection technology onto retro-reflective objects
dubbed RPT (Retro-reflective Projection Technology). Telexistence systems
provide an operator the real-time sensation of being in a remote
environment, persons in the remote environment have only a feeling
that a surrogate robot is presented, not the operator.
INTRODUCTION
Optical camouflage is a kind of active camouflage which completely
envelopes the wearer. It displays an image of the scene on the side opposite the viewer on it, so that the viewer can "see through "the wearer, rendering the wearer invisible. Optical camouflage doesn't work by way of magic. It works by taking advantage of something called Augmented-reality technology . The idea is relatively straightforward: to create the illusion of invisibility by covering an object with something that projects the scene directly behind that Object. Examples include a tiger's stripes and the battledress of a modern soldier
WORKING:
Optical camouflage doesn't work by way of magic. It works by taking advantage of something called Augmented-reality technology
Optical camouflage requires these things as well, but it also necessitates several other components. Here's everything needed to make a person appear invisible:
1. A garment made from highly reflective Material
2. A digital video camera
3. A computer
4. A projector
5. A special, half-silvered mirror called a Combiner.
For using optical camouflage, the following Steps are to be followed –
1. The person who wants to be invisible (let's Call her Person A) dons a garment That resembles a hooded raincoat. The garment is made of a special material that we’ll examine more closely in a moment.
2. An observer (Person B) stands before Person A at a specific location. At that Location, instead of seeing Person a wearing a hooded raincoat, Person B sees right through the cloak, making Person A appear to be invisible
RETROREFLECTIVITY:
The cloak that enables optical camouflage to work is made from a special material known as retro-reflective material. A retro reflective material is covered with thousands and thousands of small beads. A retro reflector is a device that sends light or other radiation back where it came from regardless of the angle of incidence, unlike a mirror, which does that only if the mirror is exactly perpendicular to the light beam. Light source is a flash a few centimeters above camera lens.This effect can be commonly obtained in Two ways:
1. With reflecting and refracting optical elements arranged so that the focal surface of the refractive element coincides with the reflective surface, In that case, the sphere surface behaves as a Concave spherical mirror with the required curvature This is conventionally known as a cat's eye retro reflector in either configuration.
