我们从理论上证明了三阶无透镜鬼衍射使用一个完全经典的非相干光源，其中的光束是由两个检测器检测。讨论了衍射图样的分辨率和可见度。结果表明，三阶鬼衍射的分辨力取决于探测平面内的横向相关长度，而可见度则受成像物体的横向长度与光源横向尺寸之比的影响。此外，我们还讨论了二阶和三阶无透镜鬼衍射的异同。
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.
