Quantum imaging with undetected photons (QIUP) is a novel interferometric technique in which the light that illuminates the object is not detected. The image is constructed from the single-photon interference pattern of the photon that never interacted with the object. The basic ingredients of QIUP are two identical pairs of correlated photons and the Zou-Wang-Mandel interferometer. This imaging technique exploits the absence of path information to induce interference. We develop a theory of QIUP in which both the object and the camera are placed in the near-field with respect to the sources. It turns out that in this configuration, the imaging is enabled by the position correlation between the twin photons. Furthermore, we also investigate the resolution limit in the near-field configuration of QIUP.
