Interferometry with Vortices

Figure 18

Fringes obtained due to interference between a vortex of charge +3 with (a) another beam with charge −3 (b) an on-axis plane wave (c) an off-axis plane wave. Interferograms obtained when both the interfering beams have off centred vortices of (d) opposite unequal charges (e) same signed unequal charges.
