Abstract:
An aerial display system comprising inexpensive optical elements and a highly brightened LCD display or similar video image display types provides floating images in an expensive enclosure. In the aerial display system, either an anti-reflective acrylic plastic layer or a circular polarizer is disposed proximate and parallel to a beam splitter so that the focal point of the floating image is proximate to the plastic layer or polarizer. This image position yields both a wider filed of view and wider perceived field of view. The aerial projection system includes a plastic spherical mirror of low cost, which includes a plastic part of at least the following descriptions: mirror surface supported by wall structures of sufficient sphericity, of a plastic material formulation, having excellent optical grade finish, a reflective metal coating, and a protective overcoat.
