An immersive augmented reality experience requires adapting the display/optical engine to the human visual system, which introduces many measurement and testing challenges. Near-eye displays often use waveguide combiners to produce superior image quality, thereby placing special demands on the metrology needs. Hence, this challenging application requires robust and state-of-the-art mechanics, and optical setup. In this study, an optical metrology system that can perform various image quality analyses on diced (eyepieces) and undiced (wafer level) waveguides is described. Our novel optical metrology system consists of a human-eye mimicking optical setup, and a multi-axis highly accurate robotics.
