Figure 10
(a) Speckle pattern produced from 63–75 µm glass spheres in air, imaged in hutch 3B at 30 keV, CB = 0, 15 mm PSW, R2 = 1 m. (b) X-ray velocimetry vector map obtained through analysis of a 5° clockwise rotation between the image pair from (a), as described in §3.4[link]. The contour map shows the relative magnitude of the motion vectors seen, with the largest shift seen at the edges of the image. Only one in five vectors are displayed in this image for ease of viewing. (c) Vector map of the X-ray velocimetry errors. All of the vectors are shown, and the magnitude is to the same scale as that shown in (b). (d)–(f) show the same images as (a)–(c); however, R2 = 5.96 m.
