Imaging with a Coherence Interferometer in Optical Astronomy
Abstract
A technique of imaging with a coherence interferometer is described which consists of postdetection processing of interferograms in the pupil space. This technique, also called incoherent holography, consists of observing the interference pattern produced by two superimposed images of the telescope pupil, one being rotated with respect to the other. Imaging through fixed aberrations and imaging through turbulence are discussed.
