Abstract: A head-mounted augmented reality device (10) includes a pair of optical modules (12) for the right and left eyes of the user, each having a collimating display source (14) optically coupled to a light guide (16) for directing image illumination towards an eye of the user. A support structure (20) is supported by the head of the user. An optical bench (22) provides a first set of alignment features (26, 28, 32, 74) for aligning and affixing the right optical module and a second set of alignment features (26, 28, 32, 74) for aligning and affixing the left optical module. A suspension arrangement suspends the optical bench relative to the support structure. The optical bench (22) provides the sole mechanical connection between the pair of optical modules (12) and the support structure (20).
