ABSTRACT OF THE DISCLOSURE An object has a light reflected or emanating therefrom projected through a symmetrical imaging device. The symmetrical imaging device contains a reference plane where the light impinging thereon has its direction changed or altered. The symmetrical imaging device relative to the reference or symmetry plane has optical properties restricting the transmitted ray from the symmetrical imaging device to lay into a normal plane containing the incident ray and the normal to the reference plane at the point of incidence. The angle of incidence is equal to the angle of transmission, but is contained on the same side of the normal (where the angle of incidence is the angle between the incident light ray and normal, the angle of transmission is the angle between the reflected light ray and normal). In the retroreflecting aspect of this invention, each light ray is reflected precisely back upon itself before or after this light ray is specularly reflected by a partially transparent medium which surface is usually coinciding with the aforementioned reference plane. In the light deflection form of the invention that uses deflection or reflection or a combination of these aspects for transmission; the device has a plane shape rather than a box shape and light from an object on one side of the device will be thrown to the opposite side of the device rather than sideways to the device in both cases. In either case, the light projected by the device forms images of objects in space. In the case of a retroreflecting device, light must be detoured as by a beam splitter, to produce a symmetrical image capable of having dimensional qualities.
