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.
