NONLINEAR RECONSTRUCTION OF THE EXIT PLANE-WAVE FUNCTION FROM PERIODIC HIGH-RESOLUTION ELECTRON-MICROSCOPY IMAGES

Two different numerical procedures, an algorithm based on the method o f simulated annealing as well as a genetic algorithm, are applied for the full non-linear reconstruction of the exit plane wave function bel onging to periodic areas of high-resolution electron microscopy images . Using simulated high-resolution images of the intermetallic alloy Ni 4Mo as a test case, the convergence behaviour and the accuracies of bo th algorithms are investigated. Based on processed experimental high-r esolution images of this alloy, a practical example of the reconstruct ion of the exit plane wave function is given.
