Strehl ratio and visibility in long-baseline stellar interferometry.
The relationship between Strehl ratio (S), the parameter most often used by those in the adaptive optics field, and visibility (V), the parameter of most interest to those working in interferometry, is investigated. It is found that if the atmospheric turbulence is assumed to be Kolmogorov, V approximately S for high Strehl ratios. At low Strehl ratios, both simulations and an analytical formulation show that the Strehl ratio underestimates the visibility.
