Densified-pupil interferometers, also called hypertelescopes, can provide direct images usable for general imaging and coronagraphy. Their properties can be deduced from a comparison with blazed diffraction gratings. Ground-based versions are considered, in the form of 10 km planar telescope arrays or of 5 km spherical arrays comparable to the Arecibo radio-telescope. Steps are taken for tests at Arecibo. Space versions are proposed for detecting extra-solar planets and, in a second step, for resolving these planets and searching photosynthetic bio-markers.
