    Abstract: The digitized in-line electron holograms recorded in an HB-5 STEM instrument were reconstructed by computer processing in place of optical reconstruction. The important parameters of the holograms, namely the spherical aberration and defocus, can be obtained from the electron Ronchigrams. The reconstructed image shows some improvement in resolution as compared with the STEM bright field image. The main limitations appear to be mechanical vibration, drift of the specimen, the relatively small number of pixels in the images, and the uncertainties in determining the spherical aberration coefficient and defocus value.
