Figure 12
Computed moiré images under the same conditions as for Fig. 8(a), but with the crystal thicknesses of (a) t1 = 0.2, t2 = 2.0 (mm) and (b) t1 = 2.0, t2 = 0.2 (mm). [tgap = 0.24 mm and in both (a) and (b).] For the image (a), the front crystal A is assumed to be strained, unlike the assumption for other computed images. See text for more details. |
