This paper establishes dynamic forward feedback correction model and regulates voluntarily the various rolling parameters by adopting hereditary neural network.

This paper establishes dynamic forward feedback correction model with the method of combining Bayes regularization and BP neural network.

Wavefront correction using liquid crystal spatial light modulator;

The influence of non-conjugate problem on the wavefront correction in the adaptive optical system;

In this paper,the basic concept of correlation analysis and wavefront correction is introduced,and then the theory of the wavefront correction system based on correlation analysis and the technical procedures of raising the precision and speed of correlation calculation are described.
