Real-time holographic 3D imaging based on multiplexing techniques and optoelectronic holograms

Multiplexing techniques for recording of 3D objects and for synthesizing of holograms are discussed. Proposals are given for recording of 3D scenes by large diameter telescope-type imaging systems applying multiple lens cameras. Suggestions are made for an optoelectronic synthesis of still and animated holograms based on photo emulsions and optoelectronic holograms respectively. Two synthesizing methods are described: an optical synthesis utilizing 2D perspective views and a synthesis based on calculating and writing of the interference pattern onto the hologram. The 2D pictures and interference pattern are procreated by optoelectronic light valves. The hologram plate consists of photoemulsions for still holograms. For animated holograms very-high-resolution optoelectronic spatial light modulators are considered. Possible types of light modulators and light valves which can be used for the real-time holographic imaging system are discussed. It is shown that animated holographic 3D images can be obtained, if the optoelectronic light modulators are available
