A new algorithm of the dislocation localization is suggested. It is based on the analysis of projections field of phase gradients. Accuracy of the algorithm is verified by numerical simulation. Special attention is focused on the precision of singular points (wavefront dislocations) screening. The algorithm is evaluated with respect to others and its advantages and drawbacks are cleared up. The method described can be included in the software of the Hartmann's sensor and be used in the full-scale experiments. Also the original algorithm of phase reconstruction is proposed and its characteristics are estimated. This algorithm requires detection of dislocation coordinates so it should be used together with the algorithm of dislocation localization. In the paper the comparison is performed of the proposed algorithm with the well known Fried's algorithm. After that the phase reconstruction technique is included into the model of a typical adaptive optics system.
