Ultra-thin camera lenses of the future could see the light of day
In the future, camera lenses could be thousands of times thinner and significantly less resource-intensive to manufacture. Researchers from Chalmers University of Technology, Sweden, now present a new technology for making the artificial materials known as ‘metasurfaces’, which consist of a multitude of interacting nanoparticles that together can control light. They could have great use in the optical technology of tomorrow.Metasurfaces can be used for optical components in portable electronics, sensors, cameras or space satellites.
