- Ground-breaking technology can make an object appear to be something else
- Technology could be used to make a jet fighter appear to be a passenger plane, or a soldier appear to be a tree
- Researchers say the technique is far simpler than current 'cloaking' devices
Chinese researchers have revealed a 'ghost cape' that can make one object appear to look like another.
The team from Southeast University in Nanjing, China say their technique is far simpler that other invisibility devices, because instead of making an object disappear entirely, it makes it look like something else. The technique scatters incoming light to create two 'ghost' images either side of the cloaked object.
'The creation of wave-dynamic illusion functionality is of great interests to various scientific communities,' the researchers led by Tie Jun Cui at Southeast University in Nanjing, China, say. They say their research could have 'unprecedented applications in the advanced-material science, camouflage, cloaking, optical and/or microwave cognition, and defense security, etc.'...
