ABSTRACT:
The apparent position of a three-dimensional volumetric image can be "translated" or moved away from image generation apparatus by employing an image translation chamber comprising two concave reflectors. In one embodiment, a reduced portion or "sector" of the image translation chamber can be provided to facilitate image translation for a restricted range of viewing angles. In another embodiment, two or more image translation chambers can be "stacked" to provide double translation of a three-dimensional image over a greater distance. In another embodiment of the invention, a bi-convex lens can be used to translate the apparent position of a three-dimensional image. Other aspects of the invention include providing a high-speed opto-mechanical shutter having a plurality of co-planar diametric holes in a cylindrical rod; the use of AOMs to accomplish very high-speed intensity modulation of a coherent light beam, which modulation can be employed to generate a periodic pattern of light "packets" or pulses; and both active and passive multi-planar optical elements used in either a reflective or transmissive mode and optionally provided with interposed layers of switchable liquid crystal material. A gas imaging chamber may be used for displaying three-dimensional images.
