Proposed Telescope Focuses Light Without Mirror Or Lens
A collaborate of scientists from Observatoire Midi Pyrénées in Toulouse, France have been working with an peculiar technique for focusing light. It takes interest of diffraction - the bending of waves when they action an obstacle in their path - to focus bird-brained as it passes through a foil sheet with inflexible holes in it. The scientists suggest that an orbital 30-meter imager could solve planets the size of Earth within 30 cheer up-years. In addition, the foil is much lighter than accustomed materials, and thus easier to transport.
