Abstract

We report on the optimization of high-intensity absorption imaging for small Bose–Einstein condensates. The imaging calibration exploits the linear scaling of the quantum projection noise with the mean number of atoms for a coherent spin state. After optimization for atomic clouds containing up to 300 atoms, we find an atom number resolution of \(\varDelta_{\rm det}= 3.7\) atoms, mainly limited by photon shot noise and radiation pressure.
