Last week we heard that researchers from Imperial college London, have published a study dealing with newly engineered metamaterials. These materials allow for light hitting them to be sped up or slowed down. Doing this, creates a zone with effectively no light, rendering that zone, and everything in it, hidden from sight, or invisible. The press release can be found here.

Our vision sensors, or eyes if you like, seem to work by collecting light rays from the environment. Waves of light hit objects, bounce off those objects and get picked up by the eye. The light then enters the eye through the cornea, passes through the pupil, and hits the retina. The picture there is received upside down, and it's up to the brain to take over and flip it around, do some filtering, put it all into context and perspective, and hopefully not pull too many tricks on us, as it often does..

Basically one could argue that it makes no difference how accurate your vision sensors are, as it still all depends on the programming and functionality of the brain, to interpret the data and make sense . . . More
