| Outline of Final Research Achievements |
We develop a low-cost adaptive optics system in optical wavelength for small telescopes. It aims to obtain high angular-resolution images that are only achieved by the Hubble space telescope or by the giant telescopes with sophisticated and expensive adaptive optics systems in near-infrared. Commercially available components will be extensively used in our system for cost reduction, in particular, we adopt a inexpensive piezoelectric deformable mirror as a key component. The fabrication of a adaptive optics system for the optical observations using the telescopes with an aperture diameter of 1-1.5 m was completed. We are making an adjustment and examining its performance in laboratory, and after that, we are planning to carry out a test observation using a small telescope in Japan. We are also preparing an observation using a small telescope built at the site where the weather condition is excellent in the world to examine the real performance of our low-cost adaptive optics system.
