Proposed Telescope Focuses Light Without Mirror Or Lens

A gang of scientists from Observatoire Midi Pyrénées in Toulouse, France have been working with an remarkable technique for focusing light. It takes use of diffraction - the bending of waves when they encounter an hitch in their path - to focus light as it passes through a thwart sheet with precise holes in it. The scientists present that an orbital 30-meter imager could work out planets the size of Earth within 30 happy-years. In addition, the foil is much lighter than habitual materials, and thus easier to transport.
