Abstract
We have studied a correlated imaging scheme using parametric downconversion stimulated with a partially coherent beam as a source. We analyze the dependence of quantum spatial correlations and image reconstruction features on the crystal length, the coherence length, and the transverse size of the seed beam in low- and high-gain regimes of parametric downconversion. We show that the visibility of ghost interference can be adjusted by varying the intensity and/or the coherence length of the seed, with improved visibility in the high-gain regime, and a visibility greater than 0.5 in the low-gain regime.
