1. An apparatus for controlling a system comprising a projection device, a target coupling-out facet and a plurality of optical paths to the target coupling-out facet, and an active wave plate arranged on the plurality of optical paths between the projection device and the target coupling-out facet, wherein the apparatus comprises at least one processor, the at least one processor being configured to:
identify one optical path of the plurality of optical paths to the target coupling-out facet;
set the active wave plate to a target state corresponding to the one optical path identified; and
cause the projection device to project a light beam comprising an image field of view component along the one optical path identified with the active wave plate set to the target state.
