摘要
By modifying the exposure sequence of the facets in a hologon during manufacture, it is intended to maximize the spatial frequency of the error especially in hologons having large numbers of facets so that the error frequency is multiplied by a large factor, thereby greatly reducing the eye's ability to detect banding problems. This method also minimizes the adjacent facet error as far as is practical.
