Abstract: A holographic display system for producing three-dimensional virtual images that are similar those of a real object seen through a conventional glass window. A basic display element comprises a lens and an image element such as conventional display screen, film, slide, or photograph. For this embodiment, the distance between the image element and the lens is approximately equal to the focal length of the lens. This setup means that different viewing angles correspond to different physical locations on the image. The apparent magnification of the image element increases as the observer moves away from the lens, which simulates the reduction in viewing angle of a real window. Selecting a distance between the lens and display that is less than the focal length of the lens allows for more accurate representation nearby objects. Other embodiments use mirror or diverging lenses. Also a variety of configurations for producing, recording, and transmitting images are described that use single or multiple cameras.
