Abstract
A method for aligning the projection of a first light source with an in-coupler of a waveguide, the method including supplying a secondary light source through an optical path of the waveguide to exit at the in-coupler of the waveguide as an exit light; determining the concentricity of the exit light with respect to the first light source; and improving the concentricity of the exit light with respect to the first light source by adjusting the positioning of the first light source such that the exit light becomes concentric with the projection of the first light source.
