Paper Abstract
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 sub-apertures illuminated by laser sources are recombined using the IRAN scheme.
The validation of the IRAN recombination consists basically in retrieving the point-spread intensity distribution
(PSID), demonstrating the conservation of the object-image convolution relation. We will introduce IRAN,
compare it to the hyper-telescope, and present the experimental results that we obtained.
