Propaedeutic Object of Speckle Interference Observation Used One-Meater Telescope of Yunnan Observatory

The speckle-images of θVir and ξ Boo binary and 32Boo star by means of speckle interference with l-meter telescope on 12 May, 1985 are introducted in this paper. The spatial mean power spectrum of ξ Boo and θ Vir is obtained and the. measured angular distance of this binary through the Fourier transform with respect to it's power spectrum is 0."99 which was agreed with M. Schneider-man's observations.
