Abstract: A classical geometrical configuration for recording an interference pattern made of circular fringes is referred and a curve is singled out where the lines orientation satisfies a Bragg condition for focusing a planar collimated beam. Insight is given for making shaped masks in planar lenses technology for integrated optics. A preliminary purely holographic verification of the focusing operation is presented.
