Abstract :
A ghost imaging scheme is used to observe the diffraction pattern of a pure phase object . It is observed that when increasing the spatial coherence the diffraction pattern disappeared from the cross-correlation, while it appeared in the autocorrelation. The cross-correlation contains information about the phase object only when the light is spatially incoherent.
