Outline of Final Research Achievements

We are developing a multi-conjugate adaptive optics system with two 140-element MEMS deformable mirrors optically conjugated to different turbulence layers at the ground and 2.6 km altitude and four 11x11-element correlating Shack-Hartmann wavefront sensors for extended sources, as the adaptive optics system capable of image monitoring the large-scale motions of atmosphere of solar planets with an 0.4 arcsec resolution over a field of view of about 50 arcsec as much as the Jovian apparent diameter at the longer wavelength than 0.5 micron on the 1.6 m Pirka telescope of the Hokkaido University. We are going to do the closed-loop tests of this adaptive optics system in laboratory and the test observations on the telescope.
