Abstract: Devices, systems, and methods corresponding to addressing misalignment in display systems are provided. A method includes using a first microelectromechanical system (MEMS) mirror, directing a first signal from a first light source to an alignment tracking waveguide. The method further includes receiving by a first photosensor a first portion of the first signal via the alignment tracking waveguide and determining a first alignment indicator associated with the first portion of the first signal. The method further includes using a second MEMS mirror, directing a second signal from a second light source to the alignment tracking waveguide. The method further includes receiving by a second photosensor a second portion of the second signal via the alignment tracking waveguide and determining a second alignment indicator associated with the second portion of the second signal.
