Iterative reconstruction method in phase-diversity imaging.

An object is iteratively reconstructed from two atmospherically degraded images, one of which is detected by shifting of a known amount of phase with respect to the other. The iterative reconstruction scheme is based on the ideas of the blind-deconvolution method and the error-reduction algorithm. An optical system to do phase shifting is proposed in which a deformable mirror is employed. Several computer simulations are conducted to exemplify the usefulness of our method.
