Abstract:
1. A volume scanning Three-Dimensional floating image display device, comprising: a real mirror image forming optical system, capable of forming the real mirror image of an object to be projected in a planar symmetric position with respect to a geometrical plane, said plane becoming a symmetry surface, and a display located under said symmetry surface and comprising a display surface for showing images as said object to be projected, and an actuator means that can move said display in a path containing a component perpendicular to said display surface; wherein said real mirror image forming optical system is a dihedral corner reflector array comprising a plurality of dihedral corner reflectors, said dihedral corner reflectors comprising of two mutually perpendicular specular surfaces arranged perpendicularly to an optical device plane, whereas said optical device plane becomes said symmetry surface, wherein by changing the images shown in said display surface in synchronicity with the movement of said display due to said actuator means, a Three-Dimensional floating image of said images will be formed in the space above said symmetry surface.
