A control algorithm for an adaptive optics system based on the focal spot radius minimization

Resumo

A control algorithm for adaptive optics systems using the focal spot of a light beam is suggested. The algorithm is based on the analytical relationship between the spot radius and a change in shape of the deformable mirror surface. A numerical simulation has been carried out, which verifies this relationship and its applicability to the wavefront correction. Some experimental results confirm the algorithm applicability for practical use.
