Abstract
Since the 80s, adaptive optics is used in astronomy to remove the effects of atmospheric turbulence, and then retrieve diffraction-limited images, even in bad seeing conditions. Thanks to its strong knowledge in Shack-Hartmann wavefront sensing and deformable mirror, Imagine Optic has developed CIAO, a simple and affordable adaptive optics system for astronomers and Free Space Optics. We present the prototype architecture, the main technological choices we did and first experimental results for two applications: - High resolution imaging on natural stars and on extended sources. - Light coupling in a single mode fiber (in VIS and SWIR). We see that CIAO can be considered now as an on the shelf adaptive optics system for FSO.
