Paper Abstract

Optical phase conjugation and two-wavelength recording in a photorefractive crystal BaTiO3 is used for real-time lateral-shear interferometry. Dispersion in uniaxial BaTiO3 crystal is used to provide perfect phase matching for two gratings of different spatial frequencies. Theoretical predictions of possible geometries are experimentally verified. The magnification effect and modulation of diffraction efficiency due to recording-reconstruction with different wavelengths are also presented.
