Motion-Driven Spectrum Expansion The cover image shows how, as a target moves, successive intensity frames add new angular views. The expanding spectral rings and increasingly sharp aircraft show how inverse synthetic aperture macroscopic Fourier ptychography converts motion trajectories into high-frequency information for non-interferometric super-resolution. See Research Article e02758 by Bowen Wang, Chao Zuo and co-workers for more details.
