We describe a scheme capable of localizing an ensemble of interacting two-level atoms. The atoms are assumed to be bunched together in a volume much smaller than an emission wavelength, and they interact with a standing wave laser field. Due to the laser-pumping of the atomic sample, it collectively emits fluorescence light with properties depending on the ensemble position in the standing wave. This relation can be described by a fluorescence intensity profile, which depends on the standing wave field parameters, the ensemble properties, and which is modified due to collective effects in the ensemble of nearby particles. We demonstrate that the intensity profile can be tailored to suit different localization setups.
