Contribution

It presents a new technique using time-encoded remote apertures to reconstruct scenes from temporal data, bypassing traditional diffraction constraints.

Findings

Achieves wavelength-scale resolution independent of distance

Reconstructs sparse scenes from a single spatial pixel or average

Overcomes diffraction limitations in remote imaging

Abstract

Imaging of scenes using light or other wave phenomena is subject to the diffraction limit. The spatial profile of a wave propagating between a scene and the imaging system is distorted by diffraction resulting in a loss of resolution that is proportional with traveled distance. We show here that it is possible to reconstruct sparse scenes from the temporal profile of the wave-front using only one spatial pixel or a spatial average. The temporal profile of the wave is not affected by diffraction yielding an imaging method that can in theory achieve wavelength scale resolution independent of distance from the scene.
