Outline of Final Research Achievements

We demonstrate a new tomographic wavefront estimation algorithm, ”multi-timestep tomographic wavefront reconstruction", which achieve more accurate tomographic estimation in wide field of view, with a multi object adaptive optics system, RAVEN, on the Subaru telescope. We analyzed the wavefront measurements data of RAVEN, and found that (1) the turbulence pattern at each altitude layer can be regarded as moving with winds, and the pattern can be regarded as "frozen" in the time scale of 100ms. Those results indicate the multi-timestep tomographic wavefront reconstruction method is effective to enlarge the field of view of tomographic wavefront estimation.
