Specially designed lens option for near-eye display testing within augmented and virtual reality headsets

The AR/VR Lens has a unique optical design specially engineered for measuring near-eye displays (NEDs), such as those integrated into virtual (VR), mixed (MR), and augmented reality (AR) headsets. The lens design simulates the size, position, and field of view of the human eye. Unlike alternative lens options, where the aperture is located inside the lens, the aperture of the AR/VR lens is located on the front of the lens, enabling positioning of the imaging system’s entrance pupil within NED headsets to view head-mounted displays (HMDs) at the same location as the human eye.

  • Replicates human eye in AR, VR, MR headsets
  • Field of view up to ±60° (120° total) horizontal
  • Pairs with high-resolution ProMetric® Imaging Colorimeters & Photometers
  • TT-ARVR™ Software for comprehensive in-headset testing

Evaluates the Full Display Field of View Experienced by Human Users

Displays 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 (FOV), 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.

ARVR Lens Aperture Comparison

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 FOV of the human eye. With the aperture at the front of the lens, the connected imaging system can capture the full FOV of the display (up to 120° horizontal, 80° vertical, 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.

Competitive measurement systems that use standard optical accessories (such as a 35mm lens) are unable to replicate the human observer’s visual experience because the aperture is integrated within the lens enclosure, limiting the full angular FOV of the display to be captured without occlusion by the NED headset hardware (frames of the eye lens). The effect is like viewing a scene through a knot hole in a fence–when the eye is position at the hole, the full FOV can be seen beyond the fence; as the eye moves away from the hole, the view becomes occluded by the edges of the fence.

Mount to ProMetric Photometers and Colorimeters

ARVR Lens with ProMetric I

The AR/VR lens is an optional mounting accessory for Radiant’s ProMetric Y Imaging Photometer or ProMetric I Imaging Colorimeter, which attaches using a custom mounting bracket to ensure stability during movement or vibration. By mounting a lens directly to a ProMetric imaging photometer or colorimeter, the AR/VR lens offers the most efficient means of measuring NEDs as a turnkey, compact camera/lens solution that requires minimal setup and integration time, equipment, or expertise. The AR/VR lens can easily be removed and replaced with standard lenses for additional display measurement applications, such as testing displays outside of headset equipment or on the production line.

Complete Toolset for AR/VR Display Measurement

Paired with a Radiant ProMetric® Imaging Photometer or Colorimeter and software, the AR/VR Lens provides a complete solution for accurate and efficient measurement of headset displays. The AR/VR Lens can be exchanged with standard lenses, enabling ProMetric imaging systems to capture high-resolution images of displays outside of the headset for pixel and sub-pixel measurements, detecting defects and anomalies in LED, LCD, OLED, microLED, and projection display components. Radiant TrueTest™ Software provides the leading display test algorithms, with the capability to sequence tests for rapid evaluation of all relevant display characteristics in a matter of seconds, applying selected tests to a single image captured by the camera. Standard tests in TrueTest include luminance, chromaticity, contrast, uniformity, mura (blemishes), pixel and line defects, and more. The application-specific TT-ARVR™ software module adds unique tests for AR/VR display analysis, which include:

  • Modulation transfer function (MTF) to evaluate image clarity based on Line Pairs, Slant Edge Contrast (ISO 12233), or Line Spread Function (LSF)
  • Image integrity evaluation including Distortion, Focus Uniformity, and Warping analyses
  • Report the horizontal, vertical, and diagonal display FOV
  • Factory distortion calibration of the lens solution to normalize wide field-of-view images for testing
  • Spatial x,y position reported in degrees (°)

With this complete Radiant solution configured for exact application needs, manufacturers can realize an efficient measurement process with the benefit of a single provider with end-to-end support.

ARVR Distortion Calibration

Wide-field-of-view images taken by a camera/lens solution before and after factory distortion calibration. Distortion calibration of each system ensures accurate spatial data is acquired by normalizing the lens effects in wide-field-of-view images.

    AR/VR Lens Key Features and Highlights:
