    "abstract": "We demonstrate a new method for non-destructive imaging of laser-cooled\natoms. This spatial heterodyne technique forms a phase image by interfering a\nstrong carrier laser beam with a weak probe beam that passes through the cold\natom cloud. The figure of merit equals or exceeds that of phase-contrast\nimaging, and the technique can be used over a wider range of spatial scales. We\nshow images of a dark spot MOT taken with imaging fluences as low as 61 pJ/cm^2\nat a detuning of 11 linewidths, resulting in 0.0004 photons scattered per atom.",
