Improving imaging resolution of shaking targets by Fourier-transform ghost diffraction

TL;DR

This paper demonstrates that Fourier-transform ghost diffraction (FGD) can achieve high-resolution imaging of shaking targets, unaffected by target movement, through phase-retrieval methods, supported by analytical, simulation, and experimental results.

Contribution

The study shows that target shaking does not affect FGD resolution, enabling high-precision imaging despite system or target movement.

Findings

Target shaking does not impact FGD resolution.

Phase-retrieval from FGD patterns achieves high-resolution imaging.

Analytical, simulation, and experimental validation support results.

Abstract

For conventional imaging, shaking of the imaging system or the target leads to the degradation of imaging resolution. In this work, the influence of the target's shaking to fourier-transform ghost diffraction (FGD) is investigated. The analytical results, which are backed up by numerical simulation and experiments, demonstrate that the quiver of target has no effect on the resolution of FGD, thus the target's imaging with high spatial resolution can be always achieved by phase-retrieval method from the FGD patterns. This approach can be applied in high-precision imaging systems, to overcome the influence of the system's shaking to imaging resolution.
