We theoretically demonstrate third-order lensless ghost diffraction by using a fully classical incoherent light source in which the light beam is detected by two detectors. The resolution and visibility of the obtained diffraction pattern are discussed. It is shown that the resolution of third-order ghost diffraction is determined by the transverse correlation length in the detection plane, while the visibility is affected by the ratio of the transverse length of the imaged object and the transverse size of the light source. Furthermore, we discuss the similarities and differences of second- and third-order lensless ghost diffraction.
