Summary[edit]
Description1225 site cold cesium atom array.png |
English: A false-color average of several images of the fluorescence emitted by individual cesium 133 atoms, which have been laser cooled from a vapor in a vacuum chamber and confined in a grid of 1225 optical traps formed by laser light. The spacing between each trapped cesium atom (red dots in the image) is 3 microns, so the entire is image is about 100 x 100 microns, roughly the size of the cross-section of a human hair. The trapped atoms are weakly illuminated by 852 nanometer (nm) laser light, which is then emitted by the atoms and imaged onto a sensitive camera (electron-multiplying charge coupled device, or EMCCD) with a high numerical aperture lens (NA=0.55). The image set is divided by the mean background noise and then processed using independent component analysis (ICA) in order to suppress the remaining noise. |

This file contains additional information such as Exif metadata which may have been added by the digital camera, scanner, or software program used to create or digitize it. If the file has been modified from its original state, some details such as the timestamp may not fully reflect those of the original file. The timestamp is only as accurate as the clock in the camera, and it may be completely wrong.
