Abstract
- Dynamic Moire´-like patterns generation by the superposition of two dynamic sinusoidal phase gratings is described. Two sinusoidal phase gratings of slightly different pitches are involved and occur in the photorefractive crystal <f>Bi12TiO20</f> (BTO). This holographic dynamic medium has been used in anisotropic two wave mixing architecture in diffusion only recording mechanism. [Copyright &y& Elsevier]
