Holograms are useful for more than interesting-looking baubles in gift shops. Materials scientists have used them for applications from stress/strain gauges to data storage systems. It turns out they would also be useful in making extraordinarily lightweight, flexible mirrors for space telescopes. A new study led by researchers at the Rensselear Polytechnic Institue shows how that might happen.
