  Quantum imaging with undetected photons (QIUP) is a unique imaging technique
that does not require the detection of the light used for illuminating the
object. The technique requires a correlated pair of photons. In the existing
implementations of QIUP, the imaging is enabled by the momentum correlation
between the twin photons. We investigate the complementary scenario in which
the imaging is instead enabled by the position correlation between the two
photons. We present a general theory and show that the properties of the images
obtained in these two cases are significantly distinct.
