Image formation for interferometric astronomical arrays requires solution of a challenging inverse problem that includes a joint solution for calibration and propagation effects as well as the unknown source brightness distribution. We consider this problem within the broader domain of adaptive optics and consider new approaches facilitated by large-scale computing. Interferometric image formation has many different domain applications and we also briefly discuss some overlapping concerns in these adjacent disciplines.
