Paper Abstract

Fringe-locking is a convenient technique for recording running holograms in photorefractive crystals (1) where the phase shift i between the recorded interference fringes and the resulting hologram is adaptively fixed to ψ = 90°. ψ = 90° means that the real part of the complex expression for the spatial charge arising electric fields modulation Esc (2) is fixed to zero. This condition allows computing the expression for the hologram velocity for different applied electric field E, and compare it to experimental data from fringe-locking experiments.
