SAN DIEGO Calif., Dec. 19, 2016 – A new test system from Gamma Scientific is the first to offer high spatial resolution color and contrast measurements for near eye displays (NED), such as virtual reality (VR) and augmented reality (AR) headsets, as well as heads up displays (HUD). Specifically, the Gamma Scientific NED Measurement System incorporates compact imaging optics which feed both an integrated camera viewing system and a low noise, high accuracy spectroradiometer. A LED spot projector (viewed using the camera) enables the operator to point the optics at a precise position within the display field, and selection of the appropriate aperture (using a motorized wheel), then permits measurements over fields of view ranging from 0.1° to 5°. The system’s graphics generator produces test patterns and color fields to measure luminance, color, contrast, uniformity, spectral transmittance, response time (flicker), transmittance MTF and left/right eye parallax measurements on subregions of displays as small as a single symbol.
The NED Measurement System is intended to aid manufacturers of head mount and heads up displays for entertainment, medical, avionics and military applications develop and produce higher quality and more consistent products. Importantly, it will enable testing to any of the testing standards currently under consideration by the IDCM committee of SID and the IEC. These standards are intended to ensure that displays are repeatable and reproducible, and meet a minimum of geometrical and performance criteria.
