Fast and efficient way of eye box measurement using wide field-of-view lens for augmented reality waveguides

We present a method to rapidly and accurately measure the eye box of Augmented Reality (AR) and Virtual Reality (VR) eyewear. We demonstrate that this rapid method measures the eye box with a fidelity comparable to slower, traditional methods. The presented rapid method uses a lens that mimics the human eye in core aspects like pupil position, pupil size and field of view to get an impression of the eyewear performance as it appears to a human user with single image capture. By combining as few as three such image captures with such a lens, one can rapidly and accurately measure the entire eye box geometry of any given AR or VR eyewear. We further demonstrate the advantages of adopting this new method by referencing the display metrology industry, where this method has already been adopted as the new metrology standard.
