Abstract
A device for providing an output beam in a direction, the device including a plate including an exit pupil; a plurality of rows of optical elements disposed substantially in a first plane, each row of optical elements in the first plane including: at least one beam splitter; and a plurality of rows of optical elements disposed substantially in a second plane, the optical elements in the second plane include mirrors, wherein the second plane is disposed between the exit pupil and the first plane, wherein the at least one beam splitter at the first plane is configured to transmit an incident beam to one of a subsequent optical element at the first plane and a subsequent optical element at the second plane before being reflected to exit through the exit pupil.
