ABSTRACT:
The present invention provides a manufacturing process (600) and method (500) for efficiently providing a multi-holographic optical element substrate unit. Upon preparation of an original continuous
on-continuous holographic optical element with uniform diffraction efficiency and marking the original continuous
on-continuous holographic optical element with predetermined alignment marks, the original continuous
on-continuous holographic optical element is cut into a predetermined number of individual holographic optical elements in accordance with the predetermined alignment marks. Then a substrate is prepared with alignment marks in accordance with the predetermined alignment marks of the individual holographic optical elements, and the individual holographic optical elements are attached to a substrate in accordance with the alignment marks.
