Abstract

We study a super-resolution synthetic aperture imaging scheme called macroscopic fourier aperture scanning imaging. By scanning the aperture on the Fourier plane of the optical system, we get a series of low resolution images of the scene. Then, the collected images are synthesized iteratively in the frequency domain. In the initial stage of recovery, the highresolution complex wave front is recovered without any phase information. The mathematical model of the imaging system is established, and the scene super-resolution imaging and phase recovery are realized through simulation. This macroscopic fourier superposition imaging technology has broad application prospects in the fields of long-distance highresolution imaging, remote sensing detection and so on.
