Abstract

Fourier synthesis of dynamic Moire-like patterns generation with square intensity profile obtained by the superposition of more than two dynamic sinusoidal phase gratings is described. The sinusoidal phase gratings of slightly different pitches are involved and occur in the photorefractive crystal Bi₁₂TiO₂₀ (BTO). This holographic dynamic medium has been used in anisotropic two wave mixing architecture in diffusion only recording mechanism.
