Zusammenfassung:An apparatus and method for recording a holographic optical element. The apparatus includes a first recording unit configured to provide a first wave front for recording the holographic optical element, a second recording unit configured to provide a second wave front for recording the holographic optical element, and (i) a deformable phase plate configured to perform wave front modulation of the first wave front when the holographic optical element is recorded, or (ii) a plurality of deformable phase plates, at least one deformable phase plate (of the plurality of deformable phase plates can be configured to perform wave front modulation of the first wave front when the holographic optical element is recorded.
