Wide-angle optical systems with combiner on the basis of the synthesized volume holograms for HMD

摘要

Designing and manufacturing of wide-angle optical systems for application in helmet mount displays are considered. Specific requirements are shown and analyzed, including: minimization of weight and size, achievement of the big field of vision, convenience of allocation on a helmet and others. Key element of HMD is combiner. Issues of designing spectral and polarizing combiners are considered. We proposed to use the synthesized volume holograms as a spectral combiner. Optical and operational properties of holographic optical elements based on volume holograms and synthesized holograms, were analyzed and compared. Research of color distortions external space at vision through combiner was carried out. Problems of optimum design of lighting system for LCOS matrixes based on high power LED are considered as well as issues of synthesis and optimization relay lens. Results of designing, the analysis and testing of optical systems for HMD are shown.
