Session 12913-45: Light measurement and quality control at different production stages of a virtual reality headset

The production of a Virtual Reality 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 display and an optical lens, which form the optical module. In a first step, the properties like luminance and chromaticity of the display and optical lens are determined. In the second step, the properties like distortion of the optical module as combination of display 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 measurement devices.
