Abstract
Techniques for augmented reality waveguide and display light engine metrology are described. In an example, a computer system causes a display light engine to emit first light from a first group of pixels of the display light engine. The computer system determines a first measurement value associated with the first light after the first light is extracted from an optical waveguide. The computer system causes the display light engine to emit second light from a second group of pixels of the display light engine. The second group is different from the first group. The computer system determines a second measurement value associated with the second light after the second light is extracted from the optical waveguide. The computer system generates, based on the first measurement value and the second measurement value, a metrology measurement indicating a property of the optical waveguide.
