Paper Abstract

The Mitaka optical-IR array (MIRA) project is a series of optical and IR interferometers by the National Astronomical Observatory of Japan. We call the first step the MIRA-I project, and the following projects are the MIRA-1.2, MIRA- II, MIRA-SG, and the MIRA-III. The MIRA-I is a prototype for demonstration of stellar interferometry, and the other projects, which are described by Sato et al. and Nishikawa et al., are practical instruments for science. The main purpose of the MIRA-I is to get stellar fringes and skill of fringe tracking. The MIRA-I instrument is located at the National Astronomical Observatory in Mitaka, Tokyo.It consists of two element telescope with 25 cm aperture placed on four meters N-S baseline. The fringe detector operates at visible or around 800 nm with high-speed sampling. In laboratory, we obtained artificial white light fringes in December 1995, and we moved the instruments to the telescope dome at January 1996. At present, we have been trying to get stellar fringes. This paper describe the current status and the progress of the MIRA-I.
