Experimental study of amplitude and phase detection limits in electron holography

The well-known advantages of electron holography are the availability of amplitude and phase of the electron wave and the resulting improvement of lateral resolution by correction of the coherent aberrations. The noise properties of the holographic method are very important: what are the smallest amplitude and phase differences detectable well above noise level in the reconstructed wave? Results of statistical evaluations collected from experimental holograms are compared with the existing theory.
