For effective emission of superlaser, a kind of monitoring system was designed with precise pointing function. By adjusting the relative position of the primary mirror and the secondary mirror, the focusing system was carried out and could image the target clearly with distance of 100~1000m. ZEMAX software was applied to optimize the optical system, the ZYGO interferometer and the large aperture collimator were served as the auxiliary devices, making the resolution ratio reach 3.38μrad＜5μrad and coaxiality meet the requirements of 4.75″≤5″. The proposed system could capture, identify and track the target, thus leading to precise pointing.
