Paper Abstract

The real time holographic correlation process was controlled and analyzed by the intentional manipulation of the intensity ratio between the writing beams in the Fourier hologram formation of an image. In this sense, and optical holographic correlation degree was defined. The experiments were performed in two wave mixing configuration based on the anisotropic self-diffraction properties of the Bi12TiO20 crystal. The correlator system was operated in the diffusion-only Bragg condition, under low power HeNe laser light illumination.
