Elimination of beam walk-off in low-coherence off-axis photorefractive holography

Whole-field photorefractive holography can be combined with low-coherence i nterferometry for three-dimensional imaging and other applications, includi ng imaging through turbid media, but the off-axis holographic recording geo metry results in a limited field of view when light of low temporal coheren ce is used. We show that tilting the energy fronts with respect to the wave fronts by use of prisms can eliminate this problem and point out that this approach will be useful for many linear and nonlinear wave-mixing experime nts.
