In a three-photon spatial correlation measurement in which we scan two of three detectors in opposite directions, we observed the enhancement of both the resolution and the contrast of the third-order spatial correlation function of chaotic thermal light in the single photon counting regime. The effect can be understood as the resolution and contrast enhancement of the point-to-point correlation function that connects the imaging plane and the object plane.
