Abstract

The measurement and evaluation methods for the optical characteristics of near-eye displays, including augmented reality (AR) and virtual reality (VR) display devices, are specified in IEC 63145-20-10. Although 2D imaging light measuring devices (LMDs) such as 2D spectroradiometers are mentioned as one type of measurement equipment, only the point measurement with a spot LMD is incorporated in the measurement procedure in that standard. Since display panels in AR/VR display devices have become smaller and had higher resolution in recent years, the point measurement with spot LMDs has become difficult to be accurately performed. Therefore, 2D imaging light spectrometry measurements are desired in the measurements for AR/VR display devices. We performed the 2D spectrometry measurement for various commercially available AR/VR display devices using our spectroradiometer (SR-5100 HM). The optical characteristics of AR/VR display devices specified in IEC 63145-20-10; luminance uniformity, chromaticity non-uniformity and contrast ratio were measured. This paper reports and compares the measurement results of the four AR/VR display devices. Our SR-5100 HM 2D spectroradiometer is capable of highly accurate evaluation of AR/VR display devices with spectral data that filter-type LMDs cannot provide.
