title: Quantification of high-resolution electron microscope images of amorphous carbon
abstract: Quantitative comparisons of experimentally obtained and simulated high-resolution electron microscope images have shown that the contrast in experimental images is usually much less than is predicted by simulations. The aim here is to investigate this loss of contrast as a function of image spatial frequency using high-resolution images of amorphous carbon. It seems that experimental images of amorphous carbon have an unexpectedly high contrast for the low spatial frequencies but that the loss of contrast is constant for frequencies above 0.5 nm(-1).
