Figure 1
Contour plots showing bits of information in an intensity measurement as a function of ZO and for (a) acentric and (b) centric intensity measurements. Contour lines are drawn, from the blue region through orange to yellow, at 0.01, 0.03, 0.1, 0.3, 1, 3 and 10 bits of information. This figure and Figs. 2–5 were prepared using Mathematica (Wolfram Research, Champaign, Illinois, USA). |
