✦ Synopsis

In the present note a real-time holographic moire-like pattern is shown. It is produced by the superposition of two rotated sinusoidal phase gratings and the result represents a promising technique for possible metrological applications. The experiments were performed in a diffusion-only recording mechanism in a photorefractive BilZTiOzc crystal illuminated by 1 = 0.633 pm from a HeNe laser light source.
