New Technology for Measuring HMD Image Quality

OptoFidelity HMD IQ

OptoFidelity HMD IQ is a complete station to test near eye displays (NED) which include an image source (display) and projection optics (lens). With HMD IQ it is possible to test various types of near eye displays and head mounted displays with fresnel, waveguide and birdbath modules. HMD IQ is designed to provide fast cycle time to test the assembled near eye display at production.

If you’re looking for a solution for temporal testing (performance testing) of HMD take a look at OptoFidelity BUDDY.

Test coverage of HMD IQ includes eyebox, inter pupillary distance, field of view (FOV, up to 120 degrees), geometric distortion, chromatic aberration, modulation transfer function (MTF), checkerboard contrast, mura and relative luminance.

OptoFidelity HMD Eye

The key part of the HMD IQ is the imaging unit called as HMD Eye. HMD Eye includes a calibrated camera and purpose built lens combination.

HMD Eye is delivered with following calibrations:

  • Focus calibration and locking with MTF50
  • MTF50 RGB Spectrum
  • Flat field
  • Luminance
  • Distortion
  • FOV/Pixel-Per-Degree
  • Dark Current/Frame
