Paper Abstract

Conjugated wavefront fidelity has been evaluated using an interferometer with a phase conjugate mirror and fringe pattern computer processing. The quantitative interpretation of the fringe patterns is performed using direct spatial phase reconstruction methods (in the space and Fourier domain). A set of algorithms for fast and accurate phase evaluation, by fringe pattern processing, were derived. The result of optical interferograms evaluation appears in terms of different phase representations. These methods have been verified by studies of the optical phase conjugation fidelity in photorefractive crystals.
