Invisibility cloaks (augmented-reality technology)
Where to use it
Pilots
Make cockpit floors transparent
Surgeons
Look through hands and instruments to make surgery be easier
Mutual telexitense
Put user's appearance onto a robot with retro-reflective material
Problems
Cannot make it be "invisible" to everyone
Hard to make it "invisible"
characteristic
to help people hide themselves
how to produce
mirage effect
sheets of carbon nanotubes, sheets of carbon wrapped up into cylindrical tubes
heated the sheets electrically, which transferred the heat to the surrounding area. As the result, effectively cloaking anything behind it with invisibility
optical camouflage technology
a digital video camera, a computer, a projector, and a special, half-silvered mirror called a combiner
A digital video camera captures the scene behind the person wearing the cloak.
The computer processes the captured image and makes the calculations necessary to adjust the still image or video so it will look realistic when it is projected.
The projector receives the enhanced image from the computer and shines the image through a pinhole-sized opening onto the combiner.
The silvered half of the mirror, which is completely reflective, bounces the projected image toward the person wearing the cloak.
The cloak acts like a movie screen, reflecting light directly back to the source, which in this case is the mirror.
Light rays bouncing off the cloak pass through the transparent part of the mirror and fall on the user's eyes. Remember that the light rays bouncing off the cloak contain the image of the scene that exists behind the person wearing the cloak
