文摘

We investigated the mechanism of atom expansion related contrast reduction in atom interferometers, proposed a mitigation strategy and evaluated its effects. We compared this strategy with other alternative strategies, discussed the possible correction when applying into other situations. We analyzed the improvement in measurement sensitivity and the potential applications of this mitigation strategy.
