Abstract:

Using the moment representation for noise in the control channels we have obtained an analytical representation for Strehl ratio. Using flexible and segmented mirrors as correctors the influence of correlated and uncorrelated Gaussian noise as well as of Poisson noise on the quality of an adaptive optics system is analyzed. It is shown that the Strehl ratio does not depend on the moment α₁ of the noise in the control channels.
