Abstract

The effect of axial correlation depth of light field on lensless ghost imaging system is investigated. We demonstrate that ghost imaging in spatial domain (GI) and Fourier-transform ghost diffraction (FRT) can be transformed by only increasing the transverse size of the source. The same results can also be obtained as the distance between the object and the test detector is increased. Conditions realizing GI, FRT, and ghost “pinhole” imaging are also discussed.
