Future imaging tools could replace lenses with microwave-sensing metamaterials

2013-01-28 18:00:48| Extremetech

Conventional imaging systems typically use a lens to map an object onto a detector plane. They acquire information as pixels, or vectors, and perform software compression after the fact. With the adoption of ever higher pixel densities we will soon reach a point where this kind of strategy is just not going to cut it anymore. A new device that uses metamaterials and compressive sensing for optimal imaging has come to our rescue.
