The importance of automatic observation systems for ground-based optical instruments is increasing since clustered measurements are being made with only a few operators. We have developed an automatic observation system for use with both a scanning and an all-sky Fabry-Perot interferometer. This paper describes the optical system of the instrument, its performance when observing auroras, and the details of the automatic observation system. The S/N ratio of the observed fringe exceeds 500, even if the auroral activity is low. Using the Internet or telephone lines, an operator can monitor and control multiple optical instruments from a remote site. In addition, we introduce a new analysis software for estimating the emission intensity, wind velocity and temperature. Once the system is further improved by modifying it to enable radio communication, the construction of remote-controlled, relocatable observatories will become feasible, representing a remarkable evolution in optical measurement technology.
