Figure 8
Comparison of the RMS error values at different sample-to-detector propagation distances. (a) RMS error (%) expressed at sample-to-detector distances of 25, 50, 75 and 100 cm. A comparison is made between the error of the whole profile as seen in red, the error of the large Perspex sphere as seen in green, and the error of the small glass spheres as seen in blue. (b) RMS error (%) expressed at the same sample-to-detector distances. A comparison is made between the reconstruction near the edge of the large Perspex sphere and the bulk of the Perspex sphere. The error bars are less than 1% RMS error, which is smaller than the data points and so are not shown. |
