Abstract

To achieve user immersion experience and wearing comfort, AR/VR glass designer targeting general consumer market strives hard for larger FOV and smaller form factor. These ultimate goals cause challenges for mass production metrology due to geometrical conflicts and test cost inefficiency. Two imaging system designs are reviewed in this paper. Both resolve above practical issues of AR/VR glass optical resolution test by shifting the complexity of the lens design to a novel optical coupler. This coupler smartly remaps discrete angular field points onto a detector with minimum spatial gap. Proposed methodologies significantly decrease the metrology equipment cost for mass production.
