Abstract
The image resolution of a conventional imagaing system is limited by aberrations produced by the intervening atmosphere. Nonlinear optical techniques like real-time holography can be used in a single-pass configuration to correct for the turbulent aberrations. In this paper the authors present analytical calculations using the modulation transfer function (MTF) approach and numerical simulations using the three dimensional wave optics code GLAD-386 of the resolution characteristics of nonlinear holographic and conventional imaging systems for extended and thin aberrators. The MTF approach under predicts for conventional images and over predicts for holographic images the effect of random apodization and anisoplanatism. For strong but thin aberrators, diffraction limited resolution with a large field of view (FOV) can be obtained using a holographic imaging system.
