Example implementation of the PRISM algorithm. a The sample’s atomic coordinates are divided up into slices. b The projected potential of each slide is computed. c Each required plane wave is calculated by using the multislice algorithm to propagate the wave through the sample. d The complex coefficients for each probe are calculated for the interpolated/cropped coordinate system, and then e each wave is multiplied by the associated coefficient and summed to generate the probe. f Final output is typically the intensity of the probe’s Fourier transform
