title: Recording and reconstruction of vector fields in a Fe-doped LiNbO₃ crystal.
abstract: We propose a flexible method to record and reconstruct vector fields with space-variant polarization distribution in c-cut Fe-doped LiNbO3, based on photorefractive two-wave mixing. To our knowledge, this is the first approach for the reconstruction of vector fields without using the photoinduced anisotropy of the recording material.
