The problem of mitigation of distorted optical signals in photorefractive crystals has been studied. An effective operating range of one-way system, based on nonlinear interaction of distorted signal with pumping formed by spatial filtering of the signal, has been optimized. To solve the problem of dynamic distortion mitigation, a new efficient numerical scheme has been developed. Using the criterion of maximal mitigation of phase and amplitude distortions, the schemes of two- and four-beam interaction in InP:Fe have been optimized.
