Abstract
With the advent of small format LCD display panels, a new level of performance and miniaturization is now possible for head mounted displays used in virtual reality systems. Recent work at the University of North Carolina has led to a rugged, compact and light weight display system well suited for glasses mounted, moderate field of view monocular displays (30 degree(s) H MUL 21 degree(s) V) as well as tiled wide field of view display systems. The optical design uses a plastic broadband polarizing beam splitter coupled with quarter wave plates and mirrors to extend the optical path length between the LCD panel and the imaging lens. This not only relaxes the performance requirements on the imaging lens but also reduces the overall depth to equal the smallest dimension of the LCD display. The cost engineered optical system is expected to weight <EQ 5 g and cost approximately $DOL15 to produce. A description of the optical design, including photographs of a plastic broadband polarizing beam splitter, is presented along with performance results of the product prototype.
