| Outline of Final Research Achievements |
A diffraction pattern from an object gives the amplitude of the diffraction wave. In experiments, however, the phase is usually missing. If we could retrieve the missing phase, we would be able to reconstruct an image of the object by the inverse Fourier transformation. This is generally known as the phase problem. This innovative new imaging method is called the diffractive imaging. The method is expected to be indispensable for the material science. We also have been doing research and published papers of the diffractive imaging. Based on the results of these researches, 3D stereo atomic resolved imaging using electron microscopy has been examined theoretically and numerically.
