Abstract
The optical device projects a three dimensional image into free space. A series of minors are aligned thereby allowing an image reflect three times between the two minors. The distance between the mirrors may be altered, changing the size and orientation of the final image. In other arrangements, the minors are aligned to permit an image to reflect five times. The minors of the device are concave, may be spherical or parabolic, and may be fragments of a spherical or parabolic minor.
