ResumoA Vacuum Generators HB5 Scanning Transmission Electron Microscope which is coupled to a PDP 11/34 minicomputer has been used to simultaneously collect and store up to three digitized, energy-filtered images. The computer and interfacing hardware control the scan of the microscope's beam in synchronization with the scan coils of the energy analyzer so images can be obtained from different spectrometer windows. Replay of the images in conjunction with an Analogic AP400 hardware array processor makes it possible to extrapolate and suppress the background signal for each separate region of the specimen.
