Abstract
Various embodiments are disclosed that relate to scanning the direction of light emitted from optical collimators. For example, one disclosed embodiment provides a system for scanning collimated light, the system comprising an optical wedge, a light injection system, and a controller. The optical wedge comprises a thin end, a thick end opposite the thin end, a viewing surface extending at least partially between the thick end and the thin end, and a back surface opposite the viewing surface. The thick end of the optical wedge further comprises an end reflector comprising a faceted lens structure. The light injection system is configured to inject light into the thin end of the optical wedge, and the controller is configured to control the location along the thin end of the optical wedge at which the light injection system injects light.
