The RSoft Photonic Component Design Suite version 2018.12 introduces new features to advance the design of optics used in augmented reality and virtual reality (AR/VR) systems. The latest RSoft release supports Synopsys’ optical design workflow for nano-textured diffractive optical elements that enable smaller, lightweight AR/VR devices with improved displays and immersive experiences.
Synopsys’ design workflow includes a seamless interface between LightTools software for virtual prototyping of light as it traverses optical and mechanical components in an AR/VR model, and the RSoft tools for fast, rigorous modeling of nano-textured optical structures. LightTools and RSoft provide a unique multi-domain simulation approach that shares Bidirectional Scattering Distribution Function (BSDF) data to help AR/VR device designers achieve superior light extraction efficiency, beam shaping, and color tuning.
In version 2018.12, the RSoft BSDF enhancements provide greater design flexibility and speed with:
- BSDF files that can be calculated for X-, Y-, or Z-oriented structures
- Support for LightTools zone rotations in RSoft BSDF user-defined optical properties
- Expanded azimuthal symmetry support for faster RSoft BSDF calculations
- Support for non-uniform wavelengths, which is useful for RGB color displays in AR/VR systems
