Two diffraction system

The light from monochromatic light source 1 is divided into two channels 3, by a 1:1 beam splitter 2, and is brought into the two-diffraction gratings 5. Two-diffraction grating generally consists of a large number of equally spaced slits, which allows connection of one channel with odd slits and the other channel with even slits 4. Then spots 7 – interference maxima – appear on the screen 6.

Advantages \• good angular resolution• low expenses• simple technological development• simple exploitation of adaptive optics• possibility to install a net of large telescopes over the Earth• lower weight for use on satellites

Proposal: Over Earth net of telescopes (30 degrees)

• high mounting not necessary• low wind influence• low gravitational influence
