Abstract

The algorithm of a segmented mirror co-phasing is described in the paper. The algorithm is based on the analysis of interference pattern, special criterion is introduced for this purpose. It is shown that initial shift of the segments must be less than half of the wavelength. To increase the dynamic range of the system the second (or even third) wavelength should be used in the algorithm. In this case the dynamic range can be increased up to 30 mkm.
