Abstract
Systems, devices, and methods for aligning a diffractive element in a wearable heads-up display ('WHUD') are described. A WHUD that includes a projector, a transparent combiner, a WHUD frame, and a diffractive optical element (DOE) embedded in the transparent combiner, requires alignment between the DOE and the eye of the user and/or the projector. A WHUD includes a DOE aligned with an eye of a user when the WHUD is worn on the head of the user. A method of aligning a DOE in a WHUD with an eye of a user when the WHUD is worn on a head of a user includes aligning a first part of the WHUD frame with a first part of the face of the user, and aligning the DOE with a second part of the WHUD frame.
