The position of a polarized atom passing through a standing light wave can be localized by observing the phase of the atomic-dipole moment in a Ramsey-type experiment. Depending on the outcome of the measurement, the diffraction pattern in the far field corresponds to atoms with their momentum changed by integer multiples of 4k. Position measurements with standard deviation of ≈ λ/40 seem to be possible with optical techniques.
