DILUTE APERTURE DIFFRACTION IMAGERY AND OBJECT RECONSTRUCTION - II - DETERMINISTIC ABERRATIONS

Replacement of a large continuum by a set of appropriately placed smal l subapertures offers a number of advantages if the object being viewe d can be reconstructed reasonably accurately from the subaperture diff raction imagery. A previous paper was devoted to this problem and nume rical calculations were carried out for the aberration-free situation. In the present paper, we extend the numerical calculations to determi ne the influence of deterministic wavefront aberration on the efficien cy of object reconstruction in the presence of measurement noise. Our calculations seem to indicate that moderate amounts of wavefront aberr ations do not appear to affect the inversion.
