Paper Abstract
For large aperture telescope, we place the significance on the jitter of the wave front parameters when we make
effort to obtain better image. We investigate the power spectral density for charactering the optical jitter for large
telescope as stochastic sequence. Limited by frequency domian property, the universal used metric, and root mean square
of wave front error (RMS WFE) cannot provide adequate information .This paper provides a complete and easy-to-use
approach to the specification of mid-and-high frequency aberration of the wave front. Additionally, we apply welch
method to the calculation of the power spectral density to achieve the accuracy result without much noise involved.
Lastly, we verify this theory by the analysis of a laser system.
