Abstract: In nearly all experiments with ultracold atoms time-of-flight pictures arethe only data available. In this paper we present an analytical strong-couplingcalculation for those time-of-flight pictures of bosons in an optical latticein the Mott phase. This allows us to determine the visibility, which quantifiesthe contrast of peaks in the time-of-flight pictures, and we suggest how to useit as a thermometer.
