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

#SYSTEM LENS SOFTWARE#

Developed specifically for AR/VR display testing, the TrueTest TT-ARVR™ software module measures luminance, chromaticity, contrast, uniformity, mura (blemishes), pixel and line defects, and adds unique tests for XR display analysis such as MTF, distortion, and focus uniformity. TrueTest™ Software offers the comprehensive range of Radiant’s display measurement capability and the ability to sequence tests for rapid automated evaluation of all relevant display characteristics in a matter of seconds. Software Toolset for AR/VR Display Measurement By mounting a lens directly to a ProMetric system, the XRE Lens provides a turnkey, compact camera/lens solution for rapid deployment of XR display testing requiring minimal setup and integration time, equipment, or expertise. The XRE Lens attaches to a Radiant ProMetric Y Imaging Photometer or ProMetric I Imaging Colorimeter using a custom mounting bracket to ensure stability during movement or vibration. Paired with a Radiant ProMetric ® Imaging Photometer or Colorimeter and software, the XRE Lens provides a complete solution for accurate and efficient in-headset display measurement.

Dual-eye solution (two integrated XRE Lens systems).

Standard solution (single XRE Lens system).

Colorimetric (luminance & chromaticity).

XRE Lens solutions are available with the following configuration options: Folded configurations also support two XRE Lens systems in a headset at once for simultaneous dual-eye (stereoscopic) measurement of left and right-eye positions-ensuring display quality is evaluated under the same conditions as viewed by the user. Resolution options up to 61 megapixels provide the necessary pixels per degree for the field of view (up to 70° V x H).Īdditionally, folded and non-folded lens options achieve near-eye measurement positions across diverse headset form factors, regardless of straps or other headgear. Depending on the measurement need, the XRE Lens can be paired with an imaging colorimeter or imaging photometer. The XRE Lens solution has multiple configuration options to address the measurement requirements of unique display types, fields of view, resolutions, and form factors. Electronic focus also enables automated Through-Focus MTF analysis, iterating through focus settings until best focus is found across the measurement image, and completing the analysis in a matter of seconds.

This means the XRE Lens system can be adjusted without manual intervention or repositioning, enabling fully automated inspection with focus settings controlled via software. Because the lens has an internal focus mechanism, the lens body does not change length when focus is changed. Precise focal distances can be set in the software to instantly focus the lens to specific virtual distances (0.5 m to infinity). The XRE Lens’s electronic focus capability eliminates these issues to provide optimal measurement efficiency. This requires equipment to be repositioned for subsequent measurements.

With extension-focus lenses, the barrel of the lens changes length while focusing, causing the measurement system’s entrance pupil to move from the eye position. Focus settings may be imprecise or shift during the measurement process. Traditional manual-focus lenses increase measurement setup time and introduce risk of error. To assess these elements correctly, the measurement system must be capable of focusing at multiple distances. Electronic Focus: Instantly Adjust to Multiple Focal PlanesĮxtended reality (XR) optical designs may incorporate multiple or variable focal planes to create a more realistic view of objects near and far. This provides flexibility to emulate human pupil size and ensure proper eye relief distance. Having no hardware, the virtual aperture of the XRE Lens solution also eliminates concerns about mechanical restrictions when positioning the entrance pupil in the headset. All aspects of the display visible to the user are comprehensively measured to ensure the intended experience. From this near-eye position, the connected imaging system can capture a 70° display field of view (FOV) as seen by the user, without obstruction by the headset hardware. The XRE Lens is designed with a virtual aperture in front of the lens, enabling the system’s optical entrance pupil to be located at the same position as the user’s eye in the headset.
