Measuring the Phase of an Optical Field from Two Intensity Measurements: Analysis of a Simple Theoretical Model

Figure 2

Decision tree illustrating the choices made by the algorithm as it steps through the unknown phase values. At each stage of the algorithm, a choice between two paths, Path 0 or Path 1, is made. A particular path through the solution space is then uniquely identified with a bit sequence. For example, if the dashed red boxes are chosen at each stage of the algorithm being chosen, this corresponds to the path .
