Abstract
The well-known advantages of electron holography are the availability of amplitude and phase of the electron wave and the resulting improvem ent of lateral resolution by correction of the coherent aberrations. T he noise properties of the holographic method are very important: what are the smallest amplitude and phase differences detectable well abov e noise level in the reconstructed wave? Results of statistical evalua tions collected from experimental holograms are compared with the exis ting theory.
