Figure 4
Comparison of intensity profiles of the first ten Pendellösung-fringe topographs of all 20 successively imaged, scanned along the X axis at a height of Y = 10.0 mm with a 3-pixel line-width. The intensity shown (ordinate axis) is as recorded by the CCD camera with no processing. Numbers at the top of the figure denote the fringe number. Numbers in the upper-right in the graphs give the recorded time of the relevant topographs. The left-hand-side ordinate scale refers to the left-hand-side graphs, and the right-hand-side ordinate scale to the right-hand-side graphs. |
