Abstract
A first waveguide of the HUD includes a first input coupler and a first output coupler. The first input coupler is configured to receive first light in a first bandwidth and provide the first light to the first output coupler. The first output coupler is configured to provide the first light in a first field of view. The first input coupler is configured to receive second light in a second bandwidth and provide the second light to the first output coupler. A second waveguide of the HUD includes a second input coupler and a second output coupler. The second input coupler is configured to receive third light in the first bandwidth and provide the third light to the second output coupler. The second output coupler is configured to provide the third light in the second field of view.
