  • Single-Shot Spatially-Resolved Imaging Magnetometry using Ultracold Atoms | TechLink
    Patent Identifier 20090272887 Status Active Categories Electronics 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 The system and method of the present invention can image the magnetic fields within an atom cloud with a high spatial resolution over the entire atom cloud in a single imaging cycle and analysis of the image provides information regarding the magnetic fields USPTO url http appft1 uspto gov netacgi nph
