Abstract
Optical phase conjugation and two-wavelength recording in a photorefra ctive crystal BaTiO3 is used for real-time lateral-shear interferometr y. Dispersion in uniaxial BaTiO3 crystal is used to provide perfect ph ase matching for two gratings of different spatial frequencies. Theore tical predictions of possible geometries are experimentally verified. The magnification effect and modulation of diffraction efficiency due to recording-reconstruction with different wavelengths are also presen ted.
