Complex Lightguide System with a 2D Eye Pupil Expansion and Human Eye Model

In order to push the limits in the field of augmented and mixed reality (AR/MR), the need for more complex lightguide systems is constantly increasing. VirtualLab Fusion provides a set of tools which enable the design and modeling of such complex systems. To demonstrate the capabilities of VirtualLab Fusion, an exemplary lightguide system with a 2D exit pupil expander in combination with a slanted grating in the outcoupler is presented. In addition, the point spread function (PSF) and modulation transfer function (MTF) are evaluated by applying a model of the human eye. Finally, an assessment of the lateral uniformity in the eyebox is demonstrated.
