AR/VR Lens: Measure Displays in HeadsetDisplays viewed near to the eye, such as those in AR/VR devices, create immersive virtual experiences. However, as display images are magnified to fill a user’s field of view, display defects are also magnified. Issues with uniformity of brightness and color, dead pixels, line defects, cloudiness, and image position become more evident to the user whose eyes are only centimeters away from display screens. In these cases, display quality testing is a critical step for product quality control. Test and measurement solutions for evaluation of NED quality include photometric imaging systems paired with software for luminance and chromaticity measurement and analysis. However, traditional optical components that measure displays like televisions and smartphones did not include design considerations for replicating the human eye’s view of visual input at the distances required for head-mounted display devices.

Specially-designed for display quality measurement in NED headsets, the Radiant Vision Systems AR/VR lens includes aperture characteristics that simulate the approximate size, position, and field of view of the human eye. With the aperture at the front of the lens, the connected imaging system can capture the full field of view (FOV) of the display (up to 120° horizontal, covering approximate human binocular FOV) without obstruction by the lens hardware. The aperture size of 3.6 mm also matches the size of a human entrance pupil, allowing displays to be measured under the same conditions as they are viewed by a human observer. This ensures that all aspects of the display visible to the user are comprehensively measured to ensure the intended experience.
