Since the discovery in 1993 of Dactyl orbiting around Ida by the Galileo spacecraft, over twenty-five binary asteroid systems have been discovered using mainly adaptive optics (AO) available on ground-based telescopes. This work focuses on the search and study of double asteroids in the main-belt, in the Trojan population and beyond Neptune's orbit. Related data were recorded in the last three years using Lick, Keck, VLT, and Palomar AO systems. However, the quality of this AO data varies significantly with the atmospheric conditions, the magnitude of the target, and its elevation. A method to automatically analyze the profile on the entire set of data was developed. This will enable one to detect a hypothetical companion around the primary asteroid. The detection curve of the images is approximate, to give a lower limit for size of a companion. AO systems capabilities will be presented. Comparison with formation models of binary asteroids will be discussed.
