Here we will present how to use crystallographic image processing to compensate for distortions caused by noise, defocus, astigmatism and crystal misalignment. The amplitudes and phases after the CTF and crystal tilt correction can be used for crystal structure determination.

Image Simulation in High Resolution Transmission Electron Microscopyent the specimen such that atomic columns are separated by distances that are of the order of the resolution of the microscope or larger. This is a condition that very often is difficult to satisfy and often limits the use of the HRTEM to studies of crystals only in low order zone-axis orientations.

Image Formation and Image Contrast in HREMhigh-resolution electron microscopy (HREM) has become a powerful technique in determining structures and defects for minute crystals. The image formation and image contrast theories are given in detail in the book “Experimental High-Resolution Electron Microscopy” written by Spence [3]. The image fo
