Inspired by a concept for discovering exoplanets with a massive space telescope, a team of researchers is developing holographic lenses that render visible and infrared starlight into either a focused image or a spectrum. The experimental method, detailed in an article appearing today in Nature Scientific Reports, could be used to create a lightweight flexible lens, many meters in diameter, that could be rolled for launch and unfurled in space.
