Abstract The imaging quality using two-detector arbitrary Nth−order intensity correlation in optics is investigated. It is theoretically demonstrated that with the order of intensity correlation N increases, the visibility of the retrieved image enhances promptly; and different n−fold intensity on one arm of the intensity correlation leads to different visibility, whereas the resolution is independent of N and n. The numerical simulation results are shown to be consistent with our theoretical analysis results. Furthermore, a particular imaging system of the two−detector Nth-order Hanbury–Brown–Twiss (HBT) type ghost diffraction is conceived by using a slit as the object, the image quality by this type of ghost diffraction is investigated. The experimental results coincide with our theoretical analysis.
