The 100m-baseline optical interferometer in China is now under construction. It consists of three 600mm telescopes and forms a maximum baseline of 100 meter. The three telescopes are placed in domes with an auxiliary room used for the adaptive optics and the dual field optics. The central optical room are used to place the delay lines and the beam combiners . The dome and the central optical room are connected by vacuum pipeline. It is hoped to compensate the opd with a residual of 100nm @ H band. The goal of imaging resolution is about 1.7mas when observation in H band. The main science goals of the telescope array are to achieve high precision astrometry, and to image the bright stars with high resolution.
The study of supermassive black hole (SMBH) is one of the most confusing astronomical topics. However, little is known about the co-evolution of SMBH and galaxies, and also the formation process of SMBH. SMBH is considered to be a celestial body on the cosmic scale. As a probe, SMBH plays an irreplaceable key role in the study of the structure and evolution of the universe. The above-mentioned scientific researches requires 10 micro arcsecond astrometry precision. Based on the differential delay interferometry, we plan to develop a prototype long baseline optical interferometry facility to achieve high precision astrometry. The planned prototype facility includes three 500mm siderostats, and the detection waveband covers both near infrared and short wave infrared (J, H). The astrometry precision of the prototype facility is expected to be at the level of ten micro arcseconds.
