- P‐4.20: Unique simulation design for crossed‐type exit pupil based on polarization volume grating Ran Wei Canran Yang Yishi Weng Yuning Zhang SID Symposium Digest of Technical Papers We propose a simulation method for two‐dimensional (2D) crossed‐type exit pupil expansion based on polarization volume grating (PVG) applied in diffractive waveguide holographic display. The functions of turning and decoupling of the PVG are realized through two continuous Bragg regions, and the spatial director distribution of liquid crystal is combined with RCWA to model its diffractive characteristics and ray tracing simulation. 10.1002/sdtp.17213 http://onlinelibrary.wiley.com/termsAndConditions#vor
