Parameter-Decoupled Superresolution with Airy-Disk-Informed Learning: Application to NGC 4486B
James Qu, Isabella L. Lee, Gang Zhang +3
Estimating the separation of two unresolved or nearly unresolved sources from recorded intensity images is difficult when source brightness, mutual coherence, and phase are unknown…

Breaking the Diffraction Barrier for Passive Sources: Parameter-Decoupled Superresolution Assisted by Physics-Informed Machine Learning
Abdelali Sajia, Bilal Benzimoun, Pawan Khatiwada +2
We present a parameter-decoupled superresolution framework for estimating sub-wavelength separations of passive two-point sources without requiring prior knowledge or control of th…
