    摘要: A method for image reconstruction in a high-resolution electron microscope is described. The Fourier transform (29) of an electron hologram (28) is composed of a central frequency domain CB = I hol,0 ( G ) and two sidebands SB+ =Ihoi,+( G ) and SB-=I 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 so that a resolution can be achieved which is considerably higher than the achievable information limit in linear image reconstruction by using the sidebands.

    摘要: A pattern formation method wherein a very small pattern composed of a desired element (atoms) is formed directly on a substrate by using atomic beam hologram technology. Quantum coherent reflection of an atomic wave is utilized. A coherent atomic beam is irradiated as a material wave, for example, upon a hologram of the transmission type to modulate the atomic beam with pattern information included in the hologram. The atomic beam having passed through and diffracted by the hologram is introduced to a reflecting plane so that the atomic beam may be quantum coherent reflected by the reflecting plane, and the atomic beam thus reflected is introduced into a substrate. A binary (two-value) hologram produced by computer synthesis is used suitably as the hologram. A hologram of the potential control type may be also used.
