Abstract:
A crystal analysis apparatus includes a first storage unit storing a crystal lattice image of a crystal region of a sample and a reference crystal lattice image for the crystal region of the sample. A first image processing unit is configured to generate a moiré image from the crystal lattice image and the reference crystal lattice image. A second storage unit stores a predetermined correspondence relationship between a moiré fringe pattern in the moiré image and a crystal defect in the crystal region or a predetermined correspondence relationship between the moiré fringe pattern in the moiré image and a crystal strain in the crystal region. An analysis unit is configured to compare the moiré fringe pattern in the moiré image to predetermined correspondence relationships stored in the second storage unit.

Claim (Index 11):
A crystal analysis method, comprising:\n obtaining a crystal lattice image of a crystal region of a sample; in a first image processing unit, generating a moir\u00e9 image from the crystal lattice image of the crystal region of the sample by using a reference crystal lattice image; in image analysis unit, comparing moir\u00e9 fringe patterns in the moir\u00e9 image to a library of pre-stored patterns having a predetermined correspondence to crystal defects or crystal strain; and detecting a crystal defect or crystal strain in the crystal region according to a similarity, calculated by the image analysis unit, between the moir\u00e9 fringe patterns of the moir\u00e9 image and at least one pre-stored pattern of the library.
