We propose a new process for making an array illuminator that combines the Talbot effect and the principle of holography. For high diffraction efficiency we use a thick phase hologram recorded in dichromated gelatin.Special conditions for the intensity uniformity of the recorded wave are required with this type of hologram. We discuss these conditions as a function of the pixel shape.
