Multi-aperture systems allow a natural method of implementing phase diversity for the joint estimation of both pupil aberrations and an image of the object. Instead of creating diversity images by means of focus adjustments, one can actuate the individual sub-apertures of the system (e.g., with a piston phase) to introduce known phase diversity.(More)
Phase diversity is a method of image-based wavefront sensing that simultaneously estimates the unknown phase aberrations of an imaging system along with an image of the object. To perform this estimation a series of images differing by a known aberration, typically defocus, are used. In this paper we present a new method of introducing the diversity unique(More)
