Construction of a Light Guide
Abstract
New applications in the area of augmented and mixed reality (AR & MR) have drawn increased attention to light-guide systems with grating regions for in- and outcoupling, and pupil-expansion purposes.
VirtualLab Fusion provides several powerful tools for the simulation and design of such systems, among them a light-guide component with flexible grating region configuration. The simulation then benefits from the “connecting field solvers” approach implemented in VirtualLab Fusion, as well as its effective non-sequential modeling technology. In this use case we present how to set up and configure the Light Guide component.

This use case demonstrates the modeling of a device of a simple “HoloLens 1”-type layout with a Light Guide component capable of guiding light with a 32° × 18° FoV.
Tutorial
Channel Resolution Accuracy Setting of Non-Sequential Field Tracing
Non-sequential field tracing is done with two steps in VirtualLab Fusion. Firstly, according to an adjustable accuracy factor, the light path through the system is detected. This light path finding can be controlled by the corresponding accuracy factor.
