Optical Breakthrough: Tunable ‘Metalenses’ Could Enable Realistic Holograms and Invisibility

Summary by The Debrief
Scientists from Linköping University in Sweden have announced an optical breakthrough in tunable polymer (plastic) metalenses that control light like traditional glass lenses with enough precision to create realistic holograms, and invisibility materials. A better understanding of the unique properties of controllable flat optics like metalenses, including their strength, scalability, and tunability, could lead to several other advanced optical …
