image enhancement of polycrystalline aluminum electron diffraction patterns ece 533 fall semester...
DESCRIPTION
Background: Electron Diffraction Patterns Tremendous amount of data present –Atomic Structure –Composition –Material Constants Simplified ray diagram of a typical TEM. The specimen would be placed above lens 1. Diffraction patterns of specimens are viewed at the back focal plane. Diffraction patterns of an A1 single crystal, polycrystalline gold, and amorphous carbon respectively. Williams, D., Carter, CB, Transmission electron microscopy, Plenum Press, NY, 1996
