Improved Dynamic Holographic Optical-Interconnection System

An improved visual display system for a helmet produces two- and three-dimensional images by use of the limited domain of spatial light modulation (SLM) values. One especially notable improvement incorporated into the design of this system is a simplification in the design of dynamic holographic optical element (HOE) switches. This system can be expected to afford immediate and calculable benefits to the United States space program; similar benefits for the military and private industry are also anticipated.
