  • Single-shot spatially-resolved imaging magnetometry using ultracold atoms
    Patent number: 7915577
    Abstract: A method and system for remotely imaging a magnetic field within an atom cloud is provided. An atom sample held in a magneto-optical trap is released, and the released atom cloud is illuminated by a Raman beam. Resonant atoms having certain velocities will absorb photon momenta from the Raman beam. The velocities of those resonant atoms will change in response to the absorbed momenta, causing a change in the travel distance of those atoms as compared with non-resonant atoms. The atom cloud is imaged by an imaging device such as a CCD camera and the presence of the resonant atoms is shown in the images as bright lines in the atom cloud. The distance traveled by the resonant atoms and therefore the separation of the lines in the image is a function of the magnetic fields in the atom cloud.
