The NED-LMD Waveguide Tester is the world's first fully automated near-eye display measurement system that mimics human visual perception for fast, accurate and repeatable characterization of next generation optical waveguide-based Augmented/Mixed Reality (AR/MR) headsets. This unique offering features a 'robotic eye' to help device manufacturers predict how the human eye will perceive their AR/MR displays, thereby quantifying end user experience through meaningful, high resolution, zero distortion and wide field of view 3D spatial and spectral measurements mapping the entire display field of view. The high accuracy, high sensitivity, and large dynamic range fiber-integrated spectroradiometer correlates spectral measurements within a two-degree spot size to the human foveal vision, thereby building a 3D dataset for complete metrology of waveguide-based AR/MR displays. This becomes especially critical as waveguide sub-assemblies typically suffer from spectral non-uniformity defects. The instrument is also uniquely equipped with a standard tunable backlighting source, the Gamma Scientific SpectralLED®. The tunable light source traceably emulates all possible environmental lighting conditions to characterize see-through contrast, transmittance, etc., through the waveguide representing how the end-device-user will perceive XR content in real life lighting conditions (i.e. ambient sunlight, illuminant D65). The main GS-NEDWave software interface features our proprietary, built-in pattern generator and includes a list of 20+ fully automated tests to obtain quick test results, interactive plots and comprehensive test reports for each device-under-test.
