Abstract:
A device or system includes a light source, an optical waveguide, and a light director. The light source emits illumination light. The optical waveguide includes a light input coupler. The light director receive the illumination light and generates shaped light. The light director adjusts the tilt angle and/or the divergence angle of the illumination light.
