Paper Abstract

An adaptive optical system dedicated to high resolution imaging can be modeled in terms of transfer loops. This model permits estimation of the response of such a system to time-varying wavefront perturbation. A block diagram describing an adaptive optic as a closed loop system is given and an analytical expression expressed in Z transform is found. In a second step, identification methods are used; the best estimates for the parameter values of the model are found using as an example the Come_On project data. Finally the responses of the model to known perturbations are compared with the experimental data recorded during the experiments of Come_On; the results are found to be in good agreement.
