Radiant Vision Systems Announces New AR/VR Lenses for Measuring Near-Eye Displays in Headset Devices

On February 1, 2018, Radiant Vision Systems, a leading provider of visual test and inspection systems for lighting and display devices, announced the release of a new AR/VR lens for Radiant Vision Systems ProMetric imaging luminance and colorimeter. The AR/VR lens features a uniquely developed optical design for measuring the visual quality of near-eye displays (NED) in virtual reality (VR), mixed reality (MR) and augmented reality (AR) headsets. The lens design simulates the size, position and field of view of the human eye, and an aperture is placed on the front of the lens to ensure that the entrance pupil of the imaging system in the NED head-mounted device is positioned in the same position as the human eye.

“In order to properly assess the quality of the near-eye display from the user's visual point of view, the measurement system should simulate the position of the human eye, maintain a similar distance to the display, and replicate the ability of the human eye to receive immersive visual inputs,” said Radug Vision Systems Chief Solution Officer Doug “The challenge is that existing brightness measurement devices are designed to evaluate more traditional displays such as televisions, smartphones, etc. In these systems, standard optics position the aperture deep inside the lens housing,” Kreysar said. Limits the camera's ability to capture the full-angle field of view of the display without being blocked by NED head-mounted hardware. In contrast, Radiant Vision Systems' AR/VR lenses have the ability to replicate the human eye in NED headsets. The aperture characteristics include the entrance pupil directly positioned on the eyepiece of the head-mounted device. In addition, we are able to measure a large field of view of 120°, which is suitable for measuring advanced VR devices."

By mounting the AR/VR lens directly to the ProMetric imaging luminance meter or colorimeter, Radiant Vision Systems now offers the industry's first solution for measuring near-eye microdisplays in head-mounted devices, including LED-based, LCD , OLED and Projection display technology . Radiant's TrueTestTM software provides industry-leading display measurement test suites and professional testing required for AR/VR measurements, enabling test sequencing, and then applying selected tests to a single image captured by the camera, ensuring that within seconds Quickly complete the evaluation of all relevant features of the display. Standard tests in TrueTest include brightness, chrominance, contrast, uniformity, Mura (瑕疵), pixel and line defects, and more. Unique tests for AR/VR display analysis include beveled contrast (MFT measurements based on ISO 12233), image distortion (for distortion characterization), image residual/ghosting, and X, Y position in degrees (°). By using Radiant's comprehensive solution for specific application needs, manufacturers can take advantage of the benefits of a single provider and end-to-end support for an efficient measurement process.

The AR/VR lens is an optional mounting accessory for Radiant's CCD-based 16 million or 29 megapixel ProMetric Y imaging luminance meter or ProMetric I imaging colorimeter. By mounting the lens directly to the ProMetric imaging luminance meter or colorimeter, the AR/VR lens provides the most efficient NED measurement method and is a compact camera/lens general contracting solution that minimizes setup and integration time. Equipment and expertise needs. You can easily remove the AR/VR lens and replace the standard lens for other display measurement applications, such as testing the display outside the headset or on the production line. Radiant Vision Systems has integrated thousands of inspection solutions into production environments around the world, with proven expertise in measurement systems to meet the specific needs of a wide range of unique display design and quality control applications.
