The present disclosure relates to a method for producing a beam shaping holographic optical element, which is configured to generate diffracted beams configured to reconstruct an image of a diffusor irrespectively of the point of impact of a pencil of light on the beam shaping holographic optical element, comprising providing a recording element, providing a master element comprising a particular pattern, forming a recording stack comprising the recording element and the master element such that the master element is arranged to the recording element in a closed-copy distance, irradiating at least a part of the recording stack with a reconstruction beam, irradiating at least a part of the recording stack with a reference beam, wherein at least one of the reconstruction beam or reference beam penetrates the master element to record the pattern of the master element onto the recording element.
