Abstract
A display system includes a substrate guided relay and a scanning projector. The scanning projector exhibits a brightness variation on a resonant scanning axis, and the substrate guided relay exhibits a brightness variation along a length of an output coupler. The scanning projector includes a brightness compensation circuit to compensate for both the brightness variation caused by the resonant scanning and the brightness variation along the length of the output coupler.
