Scientific paper

We have built a 10 cm diameter interferometer having 78 apertures of 1 mm diameter and using a direct snapshot imaging mode: the pupil densification also called hypertelescope. We have tested the direct snapshot performance of this hypertelescope with laboratory simulated multiple stars and on the sky. Characterizations of our hypertelescope limited science results but this test offers interesting perspectives for the future on the ground and in space. Densification may have applications in various fields such as providing a similar limiting magnitude but with a significantly increased angular resolution compared to a monolithic telescope with a same collecting surface.
