For quality surveillance of large-sized astronomical optics in observatory conditions a Hartmann method is widely used. In the given article problems of wavefront and deformations restoration of a main mirror are examined by use of a Hartmann technique with small-sized mask in a converging beam for the telescope testing. Is shown, that by virtue of weak conditionality of restoration task the most suitable decision of a problem is Gram-Shmidt process, allowing at appropriate modification to receive best conditionality and consequently to minimize thus error of restoration.
