Image resolution of quantum imaging with undetected photons is governed by the spatial correlations existing between the photons of a photon pair that has been generated in a nonlinear process. These correlations allow for obtaining an image of an object with light that never interacted with that object. Depending on the imaging configuration, either position or momentum correlations can be exploited. We analyze how different source parameters affect the image resolution when using spatial correlations of photons that have been generated via spontaneous parametric down conversion in a nonlinear interferometer. In particular, we discuss the intricate dependency of the resolution on the strength of the correlations within the biphoton states.
