Light measurement and quality control at different production stages of a virtual reality headset
On demand | Presented live 29 January 2024 
Abstract
The production of a VR headset is a complex process with several steps. At each step, various measurements are taken to verify quality or to characterise the component for later use. The visual system is the key component of a VR headset and consists in general of a microdisplay and an optical lens, which form the near eye display. In a first step, the properties like luminance and chromaticity of the microdisplay are determined. In the second step, the properties like distortion of the near eye display as combination of microdisplay and lens are measured. In the last step, the final VR headset is characterised for calibration and quality control. Exemplary measurements are shown for each step using imaging and spot light measuring devices.

Tobias Steinel works as a product manager at Instrument Systems GmbH. He studied Chemistry at the Georg-August University of Göttingen with a focus on physical chemistry. During his PhD he analyzed photo-chemical reactions using femtosecond fluorescence-conversion spectroscopy. As a research associate and later group leader he worked on ultra-fast IR and 4-wave-interference spectroscopy analyzing the optical structure of bio molecules at Stanford University and TU Munich. In addition, he also worked on a new type of optical imaging method for rotationally symmetric displays and center screen systems.
Tobias Steinel is responsible for Instrument Systems’ measurement portfolio in the field of AR/VR/MR applications including near-to-eye displays and microLED optical testing.
