A real-time, dynamic, free space-virtual reality, 3-D image display system which is enabled by using a unique form of Aerogel as the primary display media. A preferred embodiment of this system comprises a 3-D mosaic topographic map which is displayed by fusing four projected hologram images. In this embodiment, 4 holographic images are projected from 4 separate holograms. Each holographic image subtends a quadrant of the 4.pi. solid angle. By fusing these four holographic images, a static 3-D image such as a featured terrain map would be visible for 360 degrees in the horizontal plane and 180 degrees in the vertical plane. An input, either acquired by 3-D image sensor or generated by computer animation, is first converted into a 2-D computer generated hologram (CGH). This CGH is then downloaded into large liquid crystal (LC) panel. A laser projector illuminates the CGH-filled LC panel and generates and displays a real 3-D image in the Aerogel matrix.

[Having thus described a preferred embodiment of the invention, it being understood that the disclosure herein is only exemplary and not necessarily limiting of scope, what is claimed is:] [1.]a source of holographic image data;at least one spatial light modulator connected for being modulated by said image data;a source of reference light transmitted through said modulator to be attained in accordance with said modulating image data and forming a dynamically alterable holographic light signal;a pair of orthogonal scanners positioned for receiving said holographic light signal and sequentially projecting said light signal in two orthogonal directions for generating a time-multiplexed mosaic of the holographic light signal over a selected two-dimensional field of view; andan Aerogel matrix display medium configured as a three-dimensional, substantially transparent block and positioned for intercepting said mosaic for observing said holographic image from substantially all directions.
