03 Jan 2022 Test the visual performance of displays in augmented, mixed, and virtual reality headsets using a scientific-grade imaging system with the size and efficiency needed for production inspection. The Radiant Vision Systems AR/VR Lens solution is designed to simplify display measurement in VR headsets, AR smart glasses, and head-mounted displays without complex setup or programming. Featuring an aperture at the front of the lens, the imaging system’s entrance pupil can be positioned at the same point as the human pupil within headsets—capturing a full 120° horizontal, 80° vertical field of view (FOV) in a single measurement image. This enables quick and comprehensive analysis of all visible characteristics of the display that may be seen by the user, without rotating the imaging system or device to get the full picture.
The solution is equipped with AR/VR measurement software featuring a unique test suite for measuring the qualities of displays viewed in head-mounted devices. This automated visual inspection software controls test images displayed within the headset and runs pass/fail analyses on virtual projections to evaluate brightness, color, contrast, distortion, MTF, focus, uniformity, and more. The lens system can be integrated into production lines using factory communications for fully automated testing, as well as used in the lab for display characterization.
Key features of the AR/VR Lens solution:
- Aperture positioned at the front of the lens simulates the human eye’s entrance pupil, capturing a full FOV of near-eye display projections through headsets
- Designed to be positioned at the eye relief location
- Aperture size (3.6 mm) simulates human eye pupil size
- Lens FOV (120° horizontal, 80° vertical) captures immersive displays in a single image for evaluation
- Pairs with a high-resolution ProMetric® imaging colorimeter or photometer from Radiant Vision Systems
- Easy-to-use automated measurement control and analysis software (TT-ARVR™)
- Combination of low cost, high performance, and flexibility, designed for R&D and quality control in production
