Abstract
A waveguide combiner includes an in-coupling area, a waveguide body and an out-coupling area. The in-coupling area is configured to introduce a light beam. The waveguide body is configured to guide the light beam introduced by the in-coupling area. The out-coupling area is configured to output the light beam guided by the waveguide body. The waveguide body includes at least one of a beam-expanding part configured to expand the light beam to a predetermined direction by reflecting the light beam and a beam-folding part configured to change the light beam to a different direction by reflecting the light beam.
