Figure 4
Flowchart of the Fourier analysis algorithm of a moiré pattern recorded with horizontally aligned line gratings. The wavefront propagation angle only contains the vertical component. In order to retrieve the horizontal wavefront propagation angle, either the line gratings have to be turned by 90° or two-dimensional gratings have to used. More details can be found in the text.
