Paper Abstract

Experiments of the optical interferometer were made with two coude telescopes of 25-cm aperture which are set up by 2.6 m apart in the north-south direction. Interferometry by artificial lights were carried out. The fluctuations of fringes of He-Ne laser correlate to vibrations of the equipments. Fringes of alpha Boo were observed. However, the fringes were detected only a little because of the insufficient accuracy of delay compensation and the phase fluctuation due to the atmospheric turbulence.
