Comparison of Pendellösung-fringed diffraction images among members of the simultaneous topographs. A field near the right-hand edge in Fig. 2[link] (marked A) is observed at a higher magnification. Horizontal arrows a–c indicate the directions of displacement of the local segments of fringes just on the right of (a) or above (b and c) the arrows. Arrows are omitted in topographs where the relevant fringe segments are situated at an intermediate position in the whole side-to-side oscillation. Vertical arrows indicate images of small strain centres which show non-projective changes among the topographs. The insets also show another strain-centre image at a further higher magnification. The scale bar in topograph T1 represents 0.5 mm. The magnification of the insets is 1.67 times larger than that of the main topographs. The X and Y axes lie along the horizontal and vertical directions, respectively.
