title: Talbot array illuminator with multilevel phase gratings.
abstract: Construction of one-dimensional multilevel phase gratings is described that, when illuminated by a coherent plane wave, lead to the formation of amplitude binary gratings with an arbitrary value of the opening ratio. The gratings are proposed as array illuminators that can provide a significantly high compression factor together with a large number of uniformly illuminated points.
