Claim 17:
18. A method enacted on a head mounted display (HMD) device comprising a first image projector, a second image projector, a controller, and an optical calibration system comprising a first optical path, a second optical path, a waveguide combiner that combines the first optical path and the second optical path into a shared optical path, and a boresight sensor, the method comprising:
projecting a first calibration image along the first optical path;
projecting a second calibration image along the second optical path;
directing the first calibration image and the second calibration image to the waveguide combiner;
detecting an output of the shared optical path of the waveguide combiner via the boresight sensor, the output of the shared optical path comprising the first calibration image and the second calibration image; and
adjusting one or more of a first image of a stereoscopic image pair and a second image of the stereoscopic image pair based at least in part on an output of the boresight sensor.
