Abstract
We experimentally demonstrate a three-dimensional (3D) ghost imaging method
based on period diffraction correlation imaging. Compared with conventional ghost
imaging, our method can easily retrieve the images of different focal planes. Due to
the correlation between the disturbed object beam and the reference beams which do
not pass through any scattering, the clear images can be periodically obtained in
the uncovered zones even through a scattering medium. The analysis of the 3D imaging
resolution reveals that the proper resolution for actual demand can be achieved by
designing our devices. The implementation of this experiment is quite simple and
low-cost. It facilitates the practical applications of ghost imaging.
