  • Three dimensional real image system
    Patent number: 6568818
    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.
