Randomized trial analyzes optical system design for helmet-mounted displays, suggesting improvements for clarity.
This paper discusses questions of the design and fabrication of wide-angle optical systems for helmet-mounted displays (HDs). The requirements imposed on such systems are determined and analyzed. Questions of the design of the key elements of HDs—spectral and polarization combiners—are considered. We have proposed synthesized volume holograms as spectral combiners. The optical and operational properties of holographic optical elements based on volume holograms written by recording a volume interference pattern by the Denisyuk method are analyzed and compared. Color distortions of exterior space observed through a combiner are investigated. Questions of synthesizing a projection objective are considered. The results of the design, analysis, and testing of optical systems for HDs are presented.
