The wavefront sensors that are used in adaptive optics to sense the atmospheric turbulence have blind modes. One of those unseen modes, a waffle mode, occurs as a wavefront perturbation that produce a null or very small measurement on the wavefront sensor. In this paper we discuss a way of waffle mode mitigation by setting additional constraints in the Receding Horizon Control. The results on numerical simulations are presented. The increase in the computational load with the values of… CONTINUE READING
