Invisibility - Technological

Technological

Technology can be used theoretically or practically to render real-world objects invisible:

• Making use of real-time image displayed on a wearable display,it is possible to create a see-through effect. This is known as active camouflage.
• Though stealth technology is cited as invisibility to radar, all officially disclosed applications of the technology can only reduce the size and/or clarity of the signature detected by radar.
• In some science fiction stories, a hypothetical "cloaking device" is used to make objects invisible. On Thursday, October 19, 2006 a team effort of researchers from Britain and the US announced the development of a real cloak of invisibility, though it is only in its first stages.
• In filmmaking, people, objects, or backgrounds can be made to look invisible on camera through a process known as chroma keying.
• An artificially made meta material that is invisible on the microwave light spectrum.
