Linear sensing of speckle-pattern displacements using a photorefractive GaP crystal

Linear transformation of lateral speckle-pattern displacements into the transmitted intensity modulation is achieved in a photorefractive GaP crystal using the polarization self-modulation effect. The optical system is very simple, self-referenced, and as sensitive as an interferometer.
