Strehl Ratio

  • Richard J. Sasiela
Part of the Springer Series on Wave Phenomena book series (SSWAV, volume 18)


Strehl ratio is an important performance measure for adaptive-optics systems. Its calculation is more complicated than that of variances. Nevertheless, it is shown below that one can obtain exact expressions for the Strehl ratio for propagation through uncorrected turbulence, and through turbulence for which all modes except tilt have been corrected. Asymptotic expressions are also obtained that apply when the distortion is high.
