Innovative Systematic Design Approach for Lightguide Devices for XR-Applications

San Francisco, 2 February 2020, SPIE Photonics West

Usually, lightguide devices like AR glasses are quite complex, due to the required management of a large field of view and light of different wavelengths. Due to this complexity, numerous parameters must be considered in order to design a functional device which provides a sufficient image quality and optical performance. We will show, that this systematic approach, which is enabled by the fast physical optics technology of VirtualLab Fusion software, allows to combine the benefits of functional and parametric design and optimization strategies. Typical design tasks are discussed in detail, e.g. the trade-off between uniformity and system efficiency.
