The Talbot effect is an auto-imaging phenomenon of a grating illuminated with coherent light. The authors have demonstrated an array illuminator hologram with a large number of spots using the Talbot effect. The first tests show a good grating reconstruction but low efficiency. The use of dichromated gelatin will improve diffraction efficiency.
