“…As discussed by Moretto, Langlois and Rimmele [2], an MCAO system using tomographic wave-front conjugation optically requires a collimated beam with conjugation to different altitude layers, above the telescope. Seeking optimal performance, the deformable mirrors should be positioned at the conjugates positions to the nominal altitude of the turbulence.…”

The Sun is an ideal target for the development and application of Multi-Conjugate Adaptive Optics (MCAO). A solar MCAO system is being developed by the National Solar Observatory, Adaptive Optics Project, with the purpose of extending the corrected science field of view to 1.25Arcmin. A detailed optical set-up, design and optical performance for such a system is presented and discussed here. The preliminary results for this first MCAO/DST run, are presented in more details by Langlois et al [1] at this conference.

Since the year 2000, adaptive optics (AO) has seen the emergence of a variety of new concepts addressing particular science needs; multiconjugate adaptive optics (MCAO) is one of them. By correcting the atmospheric turbulence in 3D using several wavefront sensors and a tomographic phase reconstruction approach, MCAO aims to provide uniform diffraction limited images in the near-infrared over fields of view larger than 1 arcmin2, i.e., 10 to 20 times larger in area than classical single conjugated AO. In this review, we give a brief reminder of the AO principles and limitations, and then focus on aspects particular to MCAO, such as tomography and specific MCAO error sources. We present examples and results from past or current systems: MAD (Multiconjugate Adaptive Optics Demonstrator) and GeMS (Gemini MCAO System) for nighttime astronomy and the AO system, at Big Bear for solar astronomy. We examine MCAO performance (Strehl ratio up to 40% in H band and full width at half maximum down to 52 mas in the case of MCAO), with a particular focus on photometric and astrometric accuracy, and conclude with considerations on the future of MCAO in the Extremely Large Telescope and post–HST era.
