Abstract
The present invention discloses a novel method for effecting illumination of an arbitrary aperture. The method comprises a first step of providing a developed hologram comprising a plurality of spatially known discrete holographic optical elements that have been generated from a common arbitrary aperture. A second step comprises directing a plurality of dedicated reconstructing beams to assigned ones of the holographic optical elements, so that a composite hologram beam illuminates the arbitrary aperture.
