摘要:
An aerial projection display project an image of an object to a remote location for viewing. The display includes a pair of spherical, parabolic, or elliptical reflectors positioned and oriented relative to one another such that, when the object is placed at one or more predetermined locations, an image of such object is transmitted to the first reflector of said pair, reflected by said first reflector to the second reflector, and refocused by the second reflector as an undistorted 3-D image. In a second embodiment, the reflectors are paraboloid reflectors sharing a common axis of revolution. In another embodiment, the reflectors are elliptical reflectors each having a pair of foci. The foci lie along a common axis, and one of said foci is common to both reflectors. In a third embodiment, the reflectors are spherical reflectors The first reflector reflects a distorted image of the object to the second reflector, which corrects the distorted image from said first reflector to project a substantially undistorted image of the object.
