Future imaging tools could replace lenses with microwave-sensing metamaterials

Conventional imaging systems — like digital cameras — use a lens to map an object onto a detector plane. They acquire information as pixels, or possibly even 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. Fortunately there are much better ways to extract the information present in a visual scene. One of the more exotic among them is to use metamaterials to perform hardware compression during image acquisition.
