History of Adaptive Optics at the Canada France Hawaii Telescope (CFHT) with SCIENTIFIC RESULTS + 'IMAKA: IMaging from MAuna KeA
The goal of this project is to achieve exquisite image quality over the largest possible field of view, with a goal of a FWHM of not more than 0.3" over a square degree field in the optical domain. The narrow PSF will allow detection of fainter sources in reasonable exposure times. The characteristics of the turbulence of Mauna Kea, a very thin ground layer with excellent free seeing allows very wide fields to be corrected by GLAO, are rare and would make such an instrument unique. The Ground Layer AO..........

VASAO: Visible All-Sky Adaptive Optics
VASAO is an ambitious project that explores new conceptual direction in the field of astronomical adaptive optics. In the era of 8 meter and larger telescopes, and their instrument costs and telescope time pressure, there is a natural niche for such grounbreaking conceptual development in the 4 meter class telescope. The aim of VASAO is to provide diffraction limited imaging in the visible with 100% sky coverage; the challenge (but potential rewards) arises from the simultaneity of these requirements. To this end, CFHT is conducting a feasibility study based on the polychromatic guide star concept .

'OHANA: Optical Hawaiian Array for Nanoradian Astronomy
Increasing the resolving power of telescopes to image compact astronomical sources requires large apertures; however, 100 m is probably a technological limit for single apertures. Creating a larger aperture will require combining telescopes into interferometric arrays and using aperture synthesis techniques. The goal of `OHANA (Optical Hawaiian Array for Nanoradian Astronomy) is to investigate the value of single-mode fibers for kilometric baselines and to combine the large optical telescopes of the Mauna Kea observatories into an 800-m interferometer .
