Abstract

Phase retrieval is explored for image reconstruction using outputs from both a simulated intensity interferometer (II) and a hybrid system that combines the II outputs with partially resolved imagery from a traditional imaging telescope. Partially resolved imagery provides an additional constraint for the phase retrieval process, as well as an improved starting point for the algorithm. The benefits of this additional a priori information are explored, and when combined with standard constraints such as positivity and compact support include faster convergence, increased sensitivity, and improved image quality.
