Abstract
A head-mounted display system includes a left display assembly configured to provide left-side display light and left-side test light. A left waveguide incouples the left-side display light and outcouples the left-side display light for viewing. A left optical sensor is positioned to measure the left-side test light. A left inertial measurement unit (IMU) is configured to measure an orientation of the left display assembly. A right display assembly is configured to provide right-side display light and right-side test light. A right waveguide incouples the right-side display light and outcouples the right-side display light for viewing. A right optical sensor is positioned to measure the right-side test light. A right IMU is configured to measure an orientation of the right display assembly. A logic machine is configured to assess a stereo alignment for the left- and right-side display light.
