title: Electron emission projection imager.
abstract: A new projection type imaging system is presented. The system can directly image the field emission site distribution on a cathode surface by making use of anode screens in the standard parallel plate configuration. The lateral spatial resolution of the imager is on the order of 1-10 μm. The imaging sensitivity to the field emission current can be better than the current sensitivity of a typical electrometer, i.e., less than 1 nA.
