Paper Abstract

The known that the wave-front sensor is one of the most important element of adaptive optical system. Certainly that type of the wave-front sensor and its parameters hang from type used reference radiation (source) [1]. Particularly follows to distinguish using coherent and incoherent reference source. In this report will is described designs and algorithms of the work two sensors, first, working with coherent, and second one, with incoherent radiation. Possibilities of constructing a wave-front sensor for the adaptive system in the Big Solar Vacuum Telescope are considered. A modified correlation tracker (MCT) is proposed. The sensor is tested by measuring the displacement of the image of the solar granulation pattern in the first and second foci of the telescope under clear vision conditions.
