The present disclosure relates to a method of generating a holographic-optical beamforming element adapted to generate diffracted beams arranged to reconstruct an image of a diffuser irrespective of the point of impact of a light beam on the holographic-optical beamforming element, comprising: providing A recording element, providing a main element having a predetermined pattern, forming a recording stack comprising the recording element and the main element such that the main element is disposed to the recording element at a near-copy distance, irradiating at least a portion of the recording stack with a reconstruction beam Irradiating at least a portion of the recording stack with a reference beam, wherein at least one of the reconstruction beam or reference beam passes through the main element to record the pattern d it main element on the recording element. |
