MULTI-VIEWPOINT AERIAL IMAGE DISPLAY

摘要

A multi-viewpoint aerial image display enabling observation from multiple viewpoints by combining mirror images of objects to be projected and spatially separated from one another as real images in a narrow region in a space. The display comprises a multi-viewpoint aerial image display optical system having real mirror image forming optical systems for forming real images of the objects in plane-symmetrical positions with respect to one geometrical plane which is the symmetry plane. All the real mirror image forming optical systems are so arranged that the angle formed by given symmetry planes is below 180 degrees on the real image side with respect to the symmetry planes. The objects are so arranged as to correspond to the respective real mirror image forming optical systems.
