Practical techniques of HRTEM observations of crystal structures are described, after a brief reveiw of the basic theory of imaging based on the weak-phase-object approximation (WPOA) . The import points to obtain the crystal structure images of high quality are to (1) select thin crystals, (2) set orientation correctly under the diffraction mode and (3) take images under so-called “Scherzer's focal condition”.
