Tunable self-reference phase conjugate interferometer.
We propose a versatile self-reference phase conjugate interferometer which is based on degenerate four-wave mixing in a photorefractive crystal. A crystal of BaTiO(3) is used to store a wavefront which is compared to its displaced version at a later time. Tunable transverse and longitudinal displacements can be easily given to a wavefront. A theoretical description and experimental results of this interferometer are presented.
