The MIRA-I.2 is a 30m baseline optical interferometer located at the Mitaka campus of the National Astronomical Observatory of Japan. After the detection of the first fringes with Vega in 2002, we have continued improvement of system performance and have demonstrated stellar diameter measurement in wide band (600nm-1000nm). Recently, we begin on development of two scientific detectors: spectrometer with separate fringe tracking system and interfeometric polarimetry. Recent progress and performance of our two system is reported.
