LumiTop AR/VR Display Testing Optimized lens designs for headset and module level tests
Fast and accurate production testing for perfect user experience
The LumiTop AR/VR and LumiTop X AR systems are specifically designed for production testing of near-eye displays (NEDs) in AR/VR headsets. The AR/VR lens mimics the human eye and measures color and luminance exactly as seen by the user.
The dedicated design of the lenses provides easy access to the near-eye display and an optimal measurement position, even under spatial constraints within a fully assembled headset. Parallel operation of two LumiTop systems is possible, allowing both near-eye displays to be measured simultaneously using periscopic lens shapes. A wide field of view, various pupil sizes, and an adjustable focusing distance enable test applications across the complete production chain of NEDs and AR/VR headsets.
The LumiTop AR/VR and LumiTop X AR systems are based on the proven LumiTop principle: while an RGB camera captures the image of the near-eye display in one shot, a reference spectroradiometer measures the spectrum of the image to provide highly accurate absolute luminance and color values. Since the measurement results are fully traceable to national standards, time-consuming golden sample calibration is unnecessary. The measurement of 2D images, spectral data, and flicker values makes LumiTop one of the fastest, most comprehensive, and extremely accurate light-measurement solutions for diverse AR/VR tasks.
Instrument Systems also offers test systems for the IR light sources of a headset, often used for gesture and object recognition.
