This paper describes a method of beam-combination in the so-called hypertelescope imaging technique recently introduced by Labeyrie in optical interferometry. The method we propose is an alternative to the Michelson pupil reconfiguration that suffers from the loss of the classical object-image convolution relation. From elementary theory of...

We present an interferometric beam recombination technique which allows achromatic and direct true imaging of targets at very high angular resolution. This technique intrinsically overcomes the main problems of Labeyrie's hypertelescope design, and can be used in a nulling configuration. It is thus particularly well suited for high contrast...

We present a reanalysis of several years of DIMM data at the site of Dome C, Antarctica, to provide measurements of the coherence time τ 0. Statistics and seasonal behaviour of τ 0 are given at two heights above the ground, 3m and 8m, for the wavelength λ = 500nm. We found an annual median value of 2.9ms at the height of 8m. A few measurements...

A New Generation Infrared Sky Survey (ANGISS) is proposed for the next decade offering performances matching the requests of the new extremely large telescopes such as the E-ELT in order to prepare and follow-up their programmes. This will require the coverage of thousands of square degrees at K ˜ 25 or better, with an angular resolution of ˜...

We conducted a number of multi-color/broadband coronagraph experiments using a vacuum chamber and a binary-shaped pupil mask, which in principle should work at all wavelengths, in the context of the research and development of a stellar coronagraph to observe extra-solar planets (exoplanets) directly. The aim of this work is to demonstrate that...

In 2004, our group proposed IRAN, an alternative beam-combination technique to the so-called hypertelescope imaging method introduced by Labeyrie in the 1990s. We have recently set up a laboratory experiment aiming at validating our image densification approach instead of the pupil densification scheme of Labeyrie. In our experiment, seven...
