Interferometry with Vortices

Figure 1

Six cubic beam splitters generate a set of three plane waves: , , . These beams interfere and generate regular lattice of optical vortices. ESs are electronic shutters, which enable to capture the following interferograms: , , , . The electronic shutters are not necessary when using one-frame ( ) measurement procedure.
