ABSTRACT:
A method for image reconstruction in a high-resolution electron microscope. The Fourier transform (29) of an electron hologram (28) is obtained which is composed of a central frequency domain CB=I.sub.hol,0 (G) and two sidebands SB+=I.sub.hol,+ (G) and SB-=I.sub.hol,- (G). The two sidebands represent the linear image information. By making use of the frequencies in the central frequency domain in the image reconstruction, a non-linear image reconstruction is performed having a resolution which is considerably higher than the achievable information limit in linear image reconstruction using only the sidebands.
