Holographic display element and method of making the same |
摘要 |
A holographic display element for three-dimensionally displaying a three-dimensional model and a plane image, for example, in a superimposed manner, which is prevented from causing a change in color or a reduction in contrast of the foreground pattern at an overlap between the foreground pattern and the background pattern. The holographic display element is formed from a single reflection type volume hologram layer, wherein a foreground pattern and a background pattern are recorded so that the two patterns can be reconstructed away from each other in space and a portion of the background pattern that is shadowed by the foreground pattern as superimposed thereover is vacant.
