Abstract
An improved optical apparatus and system for producing a three-dimensional real image of an object. The apparatus includes a support member, a first concave reflective surface affixed to the support member and having an associated focal length, and a second concave reflective surface affixed to the support member. The first concave reflective surface and the second concave reflective surface are placed in substantially fixed spatial relationship to each other to define an acute angle so that when the object is appropriately placed further than the focal length of the first concave reflective surface, the apparatus produces a three-dimensional real image of the object.In preferred embodiments the first and second reflective surfaces are spherical mirrors, the support member includes an object base suitable for securely positioning the object and the support member includes an outer housing such that the object, the fight source, the first mirror and the second mirror are not externally observable by a viewer.In alternative embodiments the object can independently generate fight (e.g. a display device). In other alternative embodiments, the first and second reflective surfaces are in…
