摘要：

This paper reports real time optical holographic correlation using the Bi12TiO20 photorefractive crystal at lambda = 0.633-mu-m. The experiments were performed in the diffusion-only Bragg regime operation and are based on the anisotropic self-diffraction properties of the photorefractive material. The performance of the developed correlator is evaluated by means of the SNR concept. This system is simple and easy to control. The material employed here has high sensitivity and spatial resolution at low power HeNe laser light source illumination.
