FIELD: physics, optics.
SUBSTANCE: system for scanning collimated light comprises an optical waveguide, a system for inputting light into the first end of the optical waveguide and a controller for controlling position along the first end of the optical waveguide. The optical waveguide comprises a first end, a second end opposite the first end, a viewing surface which continues at least part between the first end and the second end, a back surface opposite the viewing surface, and an end reflector located at the second end of the optical waveguide. The end reflector comprises one or more polyhedral lens structures and a diffraction grating.
EFFECT: high efficiency of scanning collimated light.
