Figure 4
Fringe profiles measured on the experimental images in Fig. 2. Scanned at x = 5.6 mm along the y direction in the images. (a) Profile of the O image in Fig. 2(a). (b) Profile of the G image in Fig. 2(b). Deff means the effective optical density in the densitometric measurement concerned. The (+) marks in (a) and (b) note pointed-top profiles as a notable peculiarity, and (*) marks in (b) note false intensity peaks from noises (mottles). For further details, see text. |
