Research output: Contribution to journalConference articlepeer-review


We analyze the fundamental limits of source angular extent estimation for direct imaging and mode-sorting measurements as a function of source coherence length. We demonstrate that mode-sorting outperforms direct imaging in the sub-Rayleigh regime.
