Abstract: A head-mounted device may have projector, a first waveguide, a second waveguide, and an optical bridge sensor coupled between the first and second waveguides. An input coupler may couple light with a calibration pattern into the first waveguide. The calibration pattern may be included in visible or infrared light produced by the projector or may be included in infrared light produced by infrared emitters mounted to the first waveguide. An output coupler may couple the light having the calibration pattern out of the first waveguide. An additional output coupler may be used to couple visible light from the projector out of the waveguide and towards an eye box. An image sensor may generate image sensor data based on the light having the calibration pattern. Control circuitry may process the calibration pattern in the image sensor data to detect deformation or warping of the first waveguide.

Abstract: A head-mounted device may include a first display having a first projector and a first waveguide, a second display having a second projector and a second waveguide, first and second cameras, an optical sensor that couples the first waveguide to the second waveguide, and position sensors mounted to the first and second cameras and the optical sensor. The optical sensor may gather image sensor data from first image light propagating in the first waveguide and second image light propagating in the second waveguide. The cameras may capture real-world images. The position sensors may gather position measurements. Control circuitry may calibrate optical misalignment in the device by adjusting the first and/or second image light based on the image sensor data, the position measurements, and/or the world light.

Abstract: An electronic device may include a first projector, a first waveguide, a second projector, a second waveguide, and an optical sensor that couples the first waveguide to the second waveguide. A third waveguide may overlap the first waveguide, the second waveguide, and the optical sensor. The third waveguide may direct first image light from the first waveguide to the optical sensor and may direct second image light from the second waveguide to the optical sensor. The optical sensor may gather image sensor data from first image light and the second image light. The image sensor data may be free from errors in the first image light relative to the second image light associated with forces applied around the optical sensor. Control circuitry may calibrate optical misalignment in the device by adjusting the first and/or second image light based on the image sensor data.
