OPTICAL CAMOUFLAGE
What is Optical Camouflage?
o It is a camouflage technology which allows an object to blend into its surroundings
o Through which the object becomes invisible
How does it work?
o In 2005, professor at University of Tokyo –Susumu Tachi created a prototypical camouflage system
o Principle - Creating the illusion by covering an object with projection of the scene directly behind that object
What did they do?
Their system consists of-
o Retro-reflective cloak
o Camera
o Computer
o Projector
o Combiner
Retro-reflective cloak
Made of special material which reflects the light exactly in the same direction from which it comes
Camera:
It captures the image directly behind the person wearing the cloak
Computer:
It processes the image from the camera and calculates the appropriate perspective to simulate reality
Projector:
The modified image from the computer is projected on to the cloak through a projector The projector’s iris is made as small as possible
Combiner:
A special mirror to both reflect the projected image towards the cloak & let the rays from the cloak return to the observer's eye
o Transparent Rear Hatch
For drivers backing up the cars, by seeing through the transparent hatch it would be easy to know when to stop
o Fanciful application
Providing a view of the outside in windowless rooms
Drawbacks
o Large amount of external hardware required
o Surface is used as the reflector will be having the natural folds and wrinkles in the material
o Partial invisibility
o The illusion is only convincing when viewed from a certain angle
o Parallax error
Future enhancements
o With use of more sophisticated machinery we can create illusions in other electromagnetic bands
o Retro-reflective coat can be replaced with a Flexible LCD suit
o By using six cameras capturing at different angles and allowing a embedded high-speed processor to model and synthesize a scene from every point of view and thus achieving true INVISIBILITY
