    "abstract": "We demonstrate an atom localization scheme based on monitoring of the atomic\ncoherences. We consider atomic transitions in a Lambda configuration where the\ncontrol field is a standing wave field. The probe field and the control field\nproduce coherence between the two ground states. We show that this coherence\nhas the same fringe pattern as produced by a Fabry-Perot interferometer and\nthus measurement of the atomic coherence would localize the atom. Interestingly\nenough the role of the cavity finesse is played by the ratio of the intensities\nof the pump and probe. This is in fact the reason for obtaining extreme\nsubwavelenth localization. We suggest several methods to monitor the produced\nlocalization.",
