Cool Tech: Lens-less metamaterial cameras will change the way you see the world

Cameras can be pretty much considered as regular household equipment nowadays. Cheap but decent digital cameras and prosumer shooters are everywhere; even the professional-grade DSLRs are now affordable to many. But there’s one type of camera, still in the works, which promises to change the way we see things around us. No, it’s not about the latest in HD imaging it’s more on practical usage, like airport body scanners or vehicle collision avoidance technology. These cameras will be made from metamaterials, the materials whose properties don’t appear in nature, and will considerably be cheaper and smaller than the ones in existence today.
