Figure 10
We compare the maximum propagation distances as defined by both the sample shift and by the sample edge fringes. The shift-associated maximum distance z for a given δ of 3.5 × 10−7 is plotted against feature size. This is represented by the red line. The purple, blue, green and orange lines represent the fringe width-associated maximum distance for a fringe width equal to a fraction of the speckle feature size (as defined in the legend). The source-to-sample distance is 245 m, λ is 0.5 × 10−10 m. |
