A method of aligning a stencil to an eyepiece wafer includes providing the stencil, positioning the stencil with respect to a first light source, and determining locations of at least two stencil apertures. The method also includes providing the eyepiece wafer. The eyepiece wafer includes at least two eyepiece waveguides, each eyepiece waveguide including an incoupling grating and a corresponding diffraction pattern. The method further includes directing light from one or more second light sources to impinge on each of the corresponding diffraction patterns, imaging light diffracted from each incoupling grating, determining at least two incoupling grating locations, determining offsets between corresponding stencil aperture locations and incoupling grating locations, and aligning the stencil to the eyepiece wafer based on the determined offsets.
