Abstract
A volume scanning three-dimensional floating image display is constructed from 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 symmetry surface, and a display located under the symmetry surface showing images that serve as the object to be projected, and an actuator means capable of moving the display in a direction with a component perpendicular to the display surface, so by changing the displayed image synchronously with the motion of the display, the real mirror image of that image will be formed in the space on the other side of the symmetry surface as a three-dimensional floating image.
