Figure 5
(a)–(c) Detailed comparison for part of intensity profiles given in Fig. 4. (d)–(e) Plots showing the statistical characteristics of intensity variation in the 20 data images. Numbers at the bottom of graph (a) give the fringe number. In graphs (d) and (e), plots are given from top to bottom as follows: the maximum intensity measured from the mean intensity (Imax − ), the line of 1.96σI(), the number n+ of data points which are above 1.96σI(), the number n− of data points which are below −1.96σI(), the line of −1.96σI(), and the minimum intensity (Imin − ). The numbers n+ and n− refer to the right-hand-side ordinate axis. For other features, see text. |
