The quality of large-sized astronomical optics is usually tested by the Hartmann technique. For the accuracy and operational efficiency checking of this techniques different schemes it is necessary to create the mathematical model. In this paper microlens array sensor simulation results and comparison of this scheme with other modifications of this technique is presented. Algorithm, assisting to reach of successes in spots centers determination on the receiver, was created. This algorithm includes iterative the exact search and uses Fourier image of the aperture of a lens. Research of the Shack-Hartmann testing scheme microlens array based, excluding Hartmann mask application is carried out. Modeling and optimization of the measurement technique is provided, the real requirements to real requirements to elements of the circuit are determined, mathematical apparatus and algorithm of processing of results of the given circuit is developed.
