Matching One-Shot Imaging Light Measurement Devices with Goniophotometer Measurements in VR Applications

 A goniophotometer frequently acts as a gold standard in measuring XR components or headsets. The benefit of precise spectrometer results are normally correlated with longer measurement times. On the other side, imaging light measurement devices (ILMD) offer the possibility of one-shot measurements with short measurement times which make ILMD ideal for mass production with short cycle time.
To connect the measurements of ILMD and goniophotometer some pitfalls have to be considered.
In the talk, measurement data obtained with ILMD and goniophotometer of an optical modules (consisting of pancake optics and an OLED display used in VR headsets) are shown, analysed and compared. Comparability of both approaches is possible due to the traceability of reference spectrometers in both goniophotometer and ILMD.
