The setup of the LEEPS (low energy electron point source) microscope i
s described and images of carbon fibres and nanotubes are shown and co
mpared to simulated images. We used a Kirchhoff-Helmholtz type transfo
rm to reconstruct the (wave front at the) object. We also showed that
this transform can be used to reconstruct optical in-line holograms. C
