Synergy between radio and optical interferometry - image reconstruction, calibration and data analysis

摘要

Technology for image reconstruction in radio interferometry has evolved over nearly three decades with the state of the art moving towards fully automated data reduction and image reconstruction pipelines. There is potential merit in exploring areas of possible synergy with optical interferometry with the goal of transferring information both ways about lessons learnt and maybe even identifying areas where joint technical R&D may be mutually beneficial. This paper presents an overview of radio interferometric imaging and addresses the measurement of visibilities, the editing, calibration and image reconstruction steps. The state of the art is summarized and areas of potential overlap with optical interferometric data analysis and imaging are highlighted.
