Transmission electron microscope

摘要

A scanning transmission electron microscope using optical fibers as optical guiding media. The microscope obtains a high-angle scattering image or a dark-field image from electrons transmitted through a specimen. A scintillator converts electrons transmitted through the specimen into optical signals. The optical fibers couple outputs from the scintillator to the photodetector segments. The connections of the fibers with the photodetector segments are formed into arbitrary shapes.
