      abstract     = {It is demonstrated how an electron-optical arrangement
                      consisting of two electron biprisms can be used to generate
                      three-wave vortex lattices with effective lattice spacings
                      between 0.1 and 1 nm. The presence of vortices in these
                      lattices was verified by using a third biprism to perform
                      direct phase measurements via off-axis electron holography.
                      The use of three-wave lattices for nanoscale electromagnetic
                      field measurements via vortex interferometry is discussed,
                      including the accuracy of vortex position measurements and
                      the interpretation of three-wave vortex lattices in the
                      presence of partial spatial coherence.},
