Abstract:	Speckle interferometric technique is employed to record a series of hundreds of short-exposure images of several close binary stars with sub-arc second separation through a narrow band filter at the Cassegrain focus of the 2.34 meter (m) Vainu Bappu Telescope (VET), situated at Vainu Bappu Observatory (VBO), Kavalur, India. The data are recorded sequentially by a Peltier-cooled intensified CCD camera with 10 ms exposure. The auto-correlation method is applied to determine the angular separations and position angles of these binary systems.
