Abstract

Mitaka optical and InfraRed Array first stage (MIRA-I.1) was built following the first fringe detection with the previous first stage instrument called MIRA-I, rearranging its optics. It consisted of two 13 cm-diameter telescopes, collimator lens producing 8 mm propagation beams, long, fine, and fast delay lines, fringe and scintillation sensors, quadrant sensors and tip-tilt mirrors, and so on. MIRA-I.1 was operated from October 19998 to march 1999 and succeeded to get fringes of nine stars, to make stellar diameter observations, to make stellar fringe tracking experiments, and to obtain atmospheric characteristics of Mitaka site.
