Abstract:

We considered the process of wavefront reconstruction, which is based on the use of Shack–Hartmann sensor and complex-valued artificial neural network. The pixel positions are mapped on a complex plane. The process of phase reconstruction has been tested with the help of the distorted wavefront, which was obtained in the framework of a statistical model for a turbulent atmosphere. The learning of the network is based on a genetic algorithm. The process has the fast convergence, resistance to the local errors, and dynamic adaptability.

Keywords:

Shack–Hartmann sensor, wavefront reconstruction, turbulent atmosphere, complex neural network, genetic algorithm
