Abstract
A device includes one or more light guides. The device also includes a first in-coupling element configured to couple a first light having a first input field of view (“FOV”) into a first light guide, and a second in-coupling element configured to couple a second light having a second input FOV into a second light guide. The device also includes a first out-coupling element configured to couple the first light out of the first light guide as a first output light having a first output FOV, and a second out-coupling element configured to couple the second light out of the second light guide as a second output light having a second output FOV substantially non-overlapping with the first output FOV. A combination of the first output FOV and the second output FOV is larger than at least one of the first output FOV or the second output FOV.
