Comparison of two point spread functions, one created from a plane
wave and the second with an aberrated wavefront. The ratio of the height of the
aberrated to the ideal point spread function is the Strehl ratio.
quarter-wave of error in the wavefront. In general, the Strehl ratio loses its value
when aberrations of one wave are encountered (Smith 2000).
