Method for producing a beam shaping holographic optical element Arrangement for performing the same method Beam shaping holographic optical element by the same method and Display having the same optical element

摘要

The present invention is directed to a method for manufacturing a beamformed holographic optical element configured to generate a diffractive beam configured to reconstruct an image of a diffuser regardless of the point of illumination of the beam of light for the beamforming holographic optical element. The method includes the steps of providing a recording element, providing a specific pattern-containing master element, forming a recording stack including the recording element and the master element such that the master element is arranged in the recording element at a close-Irradiating at least a portion of the stack with a reconstruction beam, and irradiating at least a portion of the recording stack with a reference beam, wherein at least one of the reconstruction beam or the reference beam passes through the master element, /RTI The present invention provides an optical element manufacturing apparatus for performing the above method. The present invention provides a beamformed holographic optical element manufactured by the above method. Further, the present invention provides a display device including the beam-forming holographic optical element.;
