Abstract

A visibility-domain processing for optical interferometric imaging (VP-OII) method is proposed to model the visibility distribution of an image, and a phase retrieval technique is proposed to acquire additional visibility data from the powerspectrum and closure-phase data. This method requires only a few tunable parameters, and can be easily extended to include more data acquired from different instruments. By simulating the reconstruction of an LkHα 101 image, the proposed method proves a few hundreds times faster and is more resilient to noises than the conventional MIRA, and the image quality is comparable to noise that of conventional MIRA.
