Abstract:
A display system includes a display alignment tracker configured track the position of a first signal in a first waveguide and the position of a second signal in a second waveguide. The display alignment tracker optically multiplexes a portion of a first signal and a portion of the second signal into a combined optical signal and measures a differential between the first signal and the second signal. The differential is used to adjust the position, dimensions, or a color attribute of the first signal relative to the second signal.
