Invisio
[attachment=41799]
principle
It works on the principle bending the geometry of the space so that the light from all the directions travels around an object, rather than hitting it. so that it is unable to interact with light ,therefore the hidden object is invisible
Requirements
Optical camouflage requires these things, as well, but it also requires several other components. Here's everything needed to make a person appear invisible:
• A garment made from highly reflective material nothing but “cloak”
• A video camera
• A computer
• A projector
• A special, half--silvered mirror called a combiner
The Cloak
Made of retro-reflective material
An observer receives more of the reflected light and therefore sees a brighter reflection
Can be seen far away and outside in bright sunlight
components:
The camera captures the digital video behind the person with the cloak
The computer synthesizes the graphics and superimposes them on a real-world image
The projector shines a light beam through an opening controlled by a device called an iris diaphragm
The combiner (special mirror) is used to both reflect the projected image toward the cloak and let light rays bouncing off the cloak to return to the viewer’s eye
Head mounted display
∙It makes the system to use it more conveniently
∙They call their apparatus ahead-mounted projector (HMP) because the projection unit is an integral part of the helmet.Two projectors -- one for each eye – are required to produce a stereoscopic effect.
∙ it assembles combiner and optics in a wearable device
Conclusion
The advancement in science is making what we may have thought of as impossible, probable.
