  Ultracold polar molecules are an ideal platform for studying many-body
physics with long-range dipolar interactions. Experiments in this field have
progressed enormously, and several groups are pursuing advanced apparatus for
manipulation of molecules with electric fields as well as single-atom-resolved
in situ detection. Such detection has become ubiquitous for atoms in optical
lattices and tweezer arrays, but has yet to be demonstrated for ultracold polar
molecules. Here we present a proposal for the implementation of quantum gas
microscopy for polar molecules, and specifically discuss a technique for
spin-resolved molecular detection. We use numerical simulation of spin dynamics
of lattice-confined polar molecules to show how such a scheme would be of
utility in a spin-diffusion experiment.
