Near-eye holographic waveguide display system using novel reflective polarized volume gratings (RPVG) have lately gotten a lot of interest. However, from polarization characteristics to imaging simulation, there is no systematic approach based on RPVG. Here, a full methodology for solving this problem using the rigorous coupled wave analysis (RCWA) model is presented. This self-built RCWA model is used to examine the optical behavior of RPVG. This excellent portability of the RCWA model makes it possible for RPVG as a diffractive optical element, which is integrated into the commercial optical software Zemax via a self-compiled dynamic link library (DLL), and a full-color imaging simulation of the based-RPVG waveguide display system is obtained. Our work provides an instructive imaging analysis method using the RPVG for holographic waveguide display.
使用新型反射偏振体光栅（RPVG）的近眼全息波导显示系统近来备受关注。然而，从偏振特性到成像模拟，尚无基于RPVG的系统方法。在此，提出了一种使用严格耦合波分析（RCWA）模型解决此问题的完整方法。该自建的RCWA模型用于研究RPVG的光学行为。RCWA模型出色的可移植性使得RPVG作为衍射光学元件成为可能，它通过自编的动态链接库（DLL）集成到商业光学软件Zemax中，并获得了基于RPVG的波导显示系统的全彩色成像模拟。我们的工作提供了一种使用RPVG进行全息波导显示的指导性成像分析方法。
