Outline of Final Research Achievements

Small astronomical and site-test instruments were deployed at the Dome Fuji station of National Institute of Polar Research to study the astronomical environment. The Dome Fuji station was found to be the best site for the studies of the exoplanet atmosphere and for wide field surveys of galaxies in the early universe with infrared telescopes and cameras. The technical and engineering problems to construct mid-size infrared telescope on snow in low temperature of -80 Celsius at inland Antarctica and a multi-object infrared spectrograph dedicated to the study of exoplanet atmosphere were studied. Then a 2.5m infrared telescope and a 3-color infrared camera were designed.
