Detection of close binary systems in observations of lunar occultations at the 6-m telescope

The results of photoelectric observations of lunar occultations of 10 stars, carried out at the 6-m telescope are presented. The modified method of regularization allowing for a priori information of non-negativity of the solution is used for the restoration of the brightness strip-distribution of the occulted source. The upper limits for angular diameters of 8 stars are obtained. For one of them with brightness mV=11m.07, the resolution of 0''.0101 was achieved, the best at investigations of objects fainter than mV=10m. Two close binary systems are detected. A comparative analysis of resolution limits of lunar occultations method and speckle-interferometry is made
