Method for producing a beam shaping holographic optical element

A method is disclosed for producing a beam-shaping holographic optical element, the element being configured to generate diffracted beams configured to reconstruct an image of a diffuser irrespectively of the point of incidence of a pencil of light on the beam-shaping holographic optical element. The method comprises providing a recording element 405 and master element 402 comprising a particular pattern. A recording stack is formed with recording element and the master element arranged in a closed-copy distance. At least part of the recording stack is irradiated with a reconstruction beam 404 and a reference beam 403, wherein light passing through the master element records the pattern of the master element onto the recording element.
