Abstract
Reflective polarization volume gratings (PVGs) can be used as input and output couplers in a diffractive waveguide-based augmented reality (AR). To improve the stability and wearing comfort, a thin and lightweight full-color waveguide display is needed. In this paper, we propose a single full-color waveguide AR display based on PVGs. By analyzing the optical system, we derived the field of view limit by optimizing a three-layer PVG as an in-coupler. Pairing with a single-layer, thin PVG as an out-coupler, we can achieve a relatively uniform exit pupil of 8 mm at horizontal pupil expansion direction.
期刊介绍：
The Journal of the Society for Information Display publishes original works dealing with the theory and practice of information display. Coverage includes materials, devices and systems; the underlying chemistry, physics, physiology and psychology; measurement techniques, manufacturing technologies; and all aspects of the interaction between equipment and its users. Review articles are also published in all of these areas. Occasional special issues or sections consist of collections of papers on specific topical areas or collections of full length papers based in part on oral or poster presentations given at SID sponsored conferences.
