Uniformity Detector for Lightguide Systems
Abstract
For the performance evaluation of lightguide systems in the field of AR/MR (augmented or mixed reality) devices, the lateral uniformity of the light distribution in the eyebox is one of the most crucial parameters. In order to measure and optimize the lateral uniformity during the design process, VirtualLab Fusion provides a Uniformity Detector, which offers tools for such investigations. In this document, we demonstrate the configuration options of the Uniformity Detector.

Use Case
Modeling of a HoloLens 1 - Type Layout with 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
k-Domain Layout Visualization
We explain the physical concepts employed in the k-Layout Visualization tool and demonstrates its usage.
Tutorial
Light Guide Layout Design Tool
The Layout Design tool allows to design a custom “Hololens 1”-like augmented or mixed reality system according to the desired specifications.
Use Case
Simulation of Lightguide with 1D-1D Pupil Expander and Real Gratings
The investigation of the influence of real gratings on the efficiency and uniformity of a lightguide are of essential importance. This use case shows an example with a slanted grating as incoupler and binary surface relief grating as EPE and outcoupler.
