Accelerating AR Optical System Optimization Through Advanced Grating Simulation
アプリケーションノート
This application note demonstrates how Keysight’s RSoft enables efficient modeling, simulation, and optimization of AR waveguide gratings, including surface relief gratings (SRG), volume holographic gratings (VHG), and polarization volume gratings (PVG). By leveraging industry-proven RCWA and FDTD methods, engineers can accurately analyze diffraction efficiency, angular response, and polarization characteristics for complex grating structures.
Integrated with MOST for automated parameter scanning and multi-variable optimization, the workflow allows rapid design exploration and identification of optimal performance conditions. In addition, seamless integration with LightTools enables system-level optical analysis, supporting full AR waveguide and near-eye display optimization.
This unified workflow not only improves optical performance and uniformity but also significantly reduces simulation time and development effort, accelerating the design and deployment of next-generation AR devices.
