Image of FIG. 1.
FIG. 1.

Schematic diagram showing the geometry used in the imaging and simulation. The angle of view is from behind the x-ray film for all the images discussed.

Image of FIG. 2.
FIG. 2.

(a) grazing-incidence SWBXT image of . MPs appear as roughly oval shape with various orientations and dimensions. The MPs can be divided into two groups according to the orientation of the white elliptical contrast. Examples of each kind are shown (marked by L and R). Their images in back-reflection geometry appear as complete circular shapes (see insets on different scales), indicating that they are isolated MPs (not MP pairs or groups). (b) Schematics showing two orientations of the MP images, canted clockwise (L) or counterclockwise (R) from the vertical configuration.

Image of FIG. 3.
FIG. 3.

Simulated grazing-incidence X-ray topographic images of left-handed (a) and right-handed (b) MPs at a specimen-film distance of . reflections are simulated. Both images appear as roughly white ellipses canted clockwise (a) or counterclockwise (b) from the vertical configuration.

Image of FIG. 4.
FIG. 4.

(a) Grazing-incidence SWBXT of the crystal region containing the MPs L and R discussed in Fig. 2. Inset shows the corresponding back-reflection SWBXT image. (b) The corresponding back-reflection reticulograph. The area in the dashed box is the same region as in Fig. 2(a) and MPs 1 and 2 correspond to L and R in Fig. 2(a), respectively. The senses determined from grazing-incidence image based on ray-tracing simulation are in full agreement with the results from back-reflection reticulograph.
