title: Phase-only computer-generated hologram produced by an ion-exchange technique.
abstract: We have produced a highly efficient phase-only hologram, in which the refractive index of the substrate is modified by using an ion-exchange method. This binary phase-only hologram is produced using a conventional binary hologram as a mask for the ion exchange. A simplified theory of the phase-only hologram is presented along with a description of the fabrication method and the experimental test results.
