Abstract
We describe a wave sensing method developed for the diluted aperture of the Carlina hypertelescope and other instruments having non-monolithic mirrors. Carlina is configured like a diluted version of the Arecibo radio-telescope. The diluted primary mirror is made of fixed co-spherical segments widely spaced with respect to their size. Above this diluted mirror a helium balloon carries a gondola containing the focal optics and detector. Following the first fringes obtained on Vega with a prototype, we develop active and adaptive optics expected to respectively coherence and phase several tens of mirrors.
