Lensless Fourier-Transform Ghost Imaging with Classical Incoherent Light

摘要

The Fourier-Transform ghost imaging of both amplitude-only and pure-phaseobjects was experimentally observed with classical incoherent light at Fresneldistance by a new lensless scheme. The experimental results are in goodagreement with the standard Fourier-transform of the corresponding objects.This scheme provides a new route towards aberration-free diffraction-limited 3Dimages with classically incoherent thermal light, which have no resolution anddepth-of-field limitations of lens-based tomographic systems.
