Abstract
A head-mounted device may have a projector that emits light. The light may include visible images produced using image data and optionally infrared light. A waveguide may propagate the light and may have a first output coupler that couples the visible images out of the waveguide and towards an eye box. One or more optical sensors may generate optical sensor data based on the light emitted by the projector. Control circuitry may detect an angle between the waveguide and the projector based on the optical sensor data. The control circuitry may adjust the image data to compensate for changes in the angle over time. The optical sensors may include an optical sensor mounted to the projector and facing the waveguide and/or one or more optical sensors mounted to an optical bridge sensor.
