Abstract
A reference system configured in accordance with a particular embodiment includes a light-emitting device having a first light emitter, a second light emitter, and a housing. The housing includes a base operably connected to the first and second light emitters. The first light emitter is configured to emit a planar light region having a vertical orientation. The second light emitter is configured to emit an indicator light beam. A slope of the indicator light beam is adjustable to change a position of the indicator light beam within a vertical adjustment field. The system further includes a controller configured to cause the first and second light emitters to rotate in concert relative to the base about a vertical axis so as to rotationally reposition the planar light region and the indicator light beam in response to a detected misalignment of the planar light region.
