    "abstract": "Precision measurement of small separations between two atoms or molecules has\nbeen of interest since the early days of science. Here, we discuss a scheme\nwhich yields spatial information on a system of two identical atoms placed in a\nstanding wave laser field. The information is extracted from the collective\nresonance fluorescence spectrum, relying entirely on far-field imaging\ntechniques. Both the interatomic separation and the positions of the two\nparticles can be measured with fractional-wavelength precision over a wide\nrange of distances from bout lambda/550 to lambda/2.",
